Description

Technical Field

[0001] This application relates to the field of engineering technology, and in particular to a construction warning fence. Background Technology

[0002] Currently, construction environments inevitably involve various large and small mechanical and electrical equipment, and often result in noise and ground damage. If the construction environment is not separated from the living environment, it is very easy to cause injury and endanger people's lives and property. Construction warning fences can effectively separate the construction environment from the living environment, and have good wind protection, noise reduction and flame retardant effects.

[0003] In the existing technology, the fence includes multiple posts and multiple fence panels. The fence panels are detachably connected between two adjacent posts. In order to reduce the possibility of the fence collapsing, concrete blocks are added, and both the posts and the fence are detachably connected in the concrete blocks. Lighting lights are installed at the top of the posts, and reflective light strips are attached to the fence panels.

[0004] Regarding the aforementioned technologies, the inventors believe that the fencing can be used multiple times. When it is necessary to change the site, the columns and fencing panels can be disassembled and transported. The concrete piers are heavy and not easy to move, which increases the difficulty of transporting the concrete piers and thus increases the workload of the staff. Summary of the Invention

[0005] In order to make it easier for workers to move concrete blocks, thereby reducing the difficulty of transporting concrete blocks and thus reducing the workload of workers, this application provides a construction warning fence.

[0006] The technical solution for a construction warning fence provided in this application is as follows:

[0007] A construction site warning fence includes posts, fence panels, and concrete blocks. Multiple storage slots are provided at opposite ends of the concrete blocks near the ground. Support rods are slidably connected within the storage slots. Rollers are mounted on one end of each support rod and are rotatably connected to the ground. Storage slots are provided within the concrete blocks and are connected to each other. Fixing components for securing the support rods are provided within the storage slots.

[0008] By adopting the above technical solution, when workers transport concrete blocks, the support rod is fixed by the fixing parts. At this time, the roller can support the concrete block. When workers push the concrete block to move, the roller rolls and connects to the ground, which helps workers move the concrete block, thereby reducing the difficulty of transporting the concrete block and reducing the workload of workers.

[0009] Preferably, the concrete pier has slots at both ends on the side away from the roller, the column is inserted into the slots, the concrete pier has insertion grooves, the two ends of the insertion grooves are respectively connected to the two slots, and the enclosure plate is inserted into the insertion grooves.

[0010] By adopting the above technical solution, when workers transport concrete piers, columns, and fence panels to the construction site, they first place the concrete piers around the construction site. Then, they insert the columns into the slots on the concrete piers. After fixing the columns, they insert the fence panels into the interlocking slots and place them between two adjacent columns, thus completing the splicing of the fence.

[0011] Preferably, the inner wall of the slot is provided with a fixing groove, the fixing groove is provided with a fixing block and a first spring, the fixing block is slidably connected to the inner wall of the fixing groove, and the column is provided with a limiting groove for the fixing block to be inserted; the two ends of the first spring are respectively fixedly disposed on the fixing block and the inner wall of the fixing groove, and the slot is provided with a limiting component for limiting the fixing block.

[0012] By adopting the above technical solution, before the worker inserts the column into the slot, the fixing block is in the fixing groove and compresses the first spring under the action of the limiting component. When the worker inserts the column into the slot, the column can release the limiting of the fixing block. At the same time, the fixing block can be inserted into the limiting groove on the side wall of the column under the elastic force of the first spring, thereby reducing the possibility of the column separating from the concrete pier.

[0013] Preferably, the limiting component includes a stop plate and a second spring. The stop plate is slidably connected to the inner wall of the slot, and the two ends of the second spring are respectively fixedly disposed on the stop plate and the inner wall of the slot. The stop plate can abut against the fixing block, and the column can abut against the stop plate.

[0014] By adopting the above technical solution, before the worker inserts the column into the slot, the side wall of the abutment plate abuts against the fixing block, and the fixing block is in the fixing groove. During the process of the worker inserting the column into the slot, the column first abuts against the abutment plate. When the worker continues to push the column downward, the column pushes the abutment plate to compress the second spring. When the abutment plate moves away from the fixing block, the limiting position of the fixing block is released. At this time, the fixing block is slidably connected to the side wall of the column. When the column is completely inserted, the fixing block is aligned with the limiting groove on the side wall of the column, and the fixing block can be inserted into the limiting groove. When the worker needs to disassemble the column, firstly, the worker releases the insertion of the fixing block. The abutment plate can push the column upward under the elastic force of the first spring. At the same time, the abutment plate can abut against the fixing block, so that the worker can easily remove the column from the slot.

[0015] Preferably, the fixing member is a support block, which is slidably disposed in the storage groove, and the support rod is provided with a support groove for the support block to be inserted; the concrete pier is provided with a driving component for driving the support block to move.

[0016] By adopting the above technical solution, when the concrete is being transported, the support block is inserted into the support groove to fix the position of the support rod, allowing the roller to extend out of the storage groove and abut against the ground to support the concrete block, thereby the roller drives the concrete block to move; when the workers push the concrete block to a suitable position on the construction site, the workers drive the support block to move away from the support groove through the drive component. When the support block is detached from the support groove, the concrete block moves downward under the action of gravity, the roller is in the storage groove, and the concrete block abuts against the ground, thereby reducing the possibility of the concrete block moving.

[0017] Preferably, the inner wall of the slot is provided with a connecting groove, which is connected to the storage slot; the driving assembly includes a connecting rod and a hinge rod, one end of the connecting rod is fixedly disposed on the abutment plate, the connecting rod is slidably connected to the inner wall of the connecting groove, and the two ends of the hinge rod are respectively hinged to the connecting rod and the support block.

[0018] By adopting the above technical solution, when the worker inserts the column into the slot, the column can push the abutment plate to compress the second spring, the abutment plate moves, the connecting rod moves, the connecting rod moves, the hinge rod moves, and the hinge rod moves, causing the support block to move towards the compression of the fourth spring, thereby driving the support block away from the support groove. When the worker needs to release the roller out of the storage groove to move the concrete block, the worker first takes the column out of the slot, the abutment plate moves upward under the force of the second spring, thereby causing the connecting rod to move upward, the connecting rod moves, causing the hinge rod to move, thereby driving the support block to move closer to the support rod. At this time, the support block abuts against the side wall of the support rod, and the fourth spring is in a compressed state.

[0019] Preferably, a third spring is provided in the storage slot, and the two ends of the third spring are respectively fixed to the support rod and the inner wall of the storage slot.

[0020] By adopting the above technical solution, when the concrete block moves towards the ground and comes into contact with the ground, the third spring is compressed and comes into contact with the support rod; when the staff needs to disassemble and transport the enclosure, after the staff disassembles the column and the enclosure panel, the staff briefly lifts both ends of the concrete block in turn. When the concrete block is lifted, the ground has no supporting force on the roller, and the support rod is pushed by the elastic force of the third spring to drive the roller to move away from the storage tank, so that the roller moves outside the storage tank.

[0021] Preferably, a connecting block is fixedly installed inside the storage tank, and a fourth spring is fixedly installed on the connecting block, with the other end of the fourth spring fixedly installed on the support block.

[0022] By adopting the above technical solution, the fourth spring is always in a compressed state. When the support block is inserted into the support groove, the fourth spring pushes the support block towards the support groove under the force of the spring, thereby reducing the possibility of the support block detaching from the support groove. When the support rod moves downward under the force of the third spring, the support rod is slidably connected to the support block. When the support groove is directly opposite the support block, the support block is inserted into the support groove under the force of the fourth spring, thereby reducing the movement of the support rod and thus fixing the roller outside the storage groove to support the concrete pier.

[0023] Preferably, a tie rod is fixedly installed on the fixing block, and a sliding groove is provided on the concrete pier, with the tie rod slidably connected to the inner wall of the sliding groove.

[0024] By adopting the above technical solution, when the construction at the site is completed and the workers need to remove the fence, the workers first remove the fence panel, and then pull the lever to move away from the column. The movement of the lever can drive the fixing block to compress the first spring and move away from the limiting groove. When the fixing block is disengaged from the limiting groove, the column moves under the push of the abutment plate. At this time, the fixing block is blocked in the fixing groove by the abutment plate, which makes it easier for the workers to remove the column.

[0025] Preferably, the inner wall of the insertion slot is provided with a placement slot, the inner wall of the placement slot is slidably connected with a placement plate, one end of the placement plate is provided with an inclined surface, the baffle plate can abut against the placement plate, and the placement slot is provided with a blocking component that can prevent the placement plate from falling off.

[0026] By adopting the above technical solution, when the staff inserts the enclosure board into the insertion slot, the enclosure board abuts against the placement board through the inclined surface of the placement board and pushes the placement board to move along the placement slot, so that the placement board is exposed from the placement slot. The staff can pull the placement board according to the size of the items to be placed.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When workers transport concrete blocks, the support rods are fixed by the fasteners. At this time, the rollers can support the concrete blocks. When workers push the concrete blocks to move, the rollers roll and connect to the ground, which helps workers move the concrete blocks, thereby reducing the difficulty of transporting concrete blocks and reducing the workload of workers.

[0029] 2. When the concrete is being transported, the support block is inserted into the support groove to fix the position of the support rod, allowing the roller to extend out of the storage groove and abut against the ground to support the concrete block. The roller then moves the concrete block. When the workers push the concrete block to a suitable position on the construction site, they drive the support block away from the support groove using the drive assembly. After the support block leaves the support groove, the concrete block moves downward under the influence of gravity. The roller is in the storage groove, and the concrete block abuts against the ground, thus reducing the possibility of the concrete block shifting.

[0030] 3. When the concrete block moves towards the ground and comes into contact with the ground, the third spring is compressed and comes into contact with the support rod; when the staff needs to disassemble and transport the enclosure, after the staff disassembles the column and the enclosure panel, the staff briefly lifts both ends of the concrete block in turn. When the concrete block is lifted, the ground has no supporting force on the roller, and the support rod is pushed by the elastic force of the third spring to drive the roller to move away from the storage tank, so that the roller moves outside the storage tank.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses a construction site warning fence. For example... Figure 1 and Figure 2 As shown, and in combination Figure 3 As shown, the structure includes a column 1, a fence 2, and a concrete pier 3. The column 1, the fence 2, and the concrete pier 3 are all rectangular. Two storage slots 4 are provided at opposite ends of the bottom sidewall of the concrete pier 3. The two storage slots 4 at the same end are symmetrically arranged and are grouped together. The storage slots 4 extend vertically and are slidably connected to a support rod 5 in the vertical direction. The support rod 5 is rectangular and has a roller 6 installed at its bottom end. The roller 6 can roll and connect to the ground. Storage slots 7 are provided at both ends of the concrete pier 3. The two storage slots 7 are respectively arranged to correspond to the two groups of storage slots 4. The storage slots 7 are connected to the two adjacent storage slots 4. The storage slots 7 are provided with two sets of fixing parts for fixing the two opposing support rods 5.

[0039] like Figure 1 and Figure 2 As shown, and in combination Figure 3 As shown, when workers need to transport the concrete block 3 to the construction site, the support rod 5 is first fixed by the fixing parts. At this time, the roller 6 rolls on the ground and can support the weight of the concrete block 3. When workers push the concrete block 3 to move, the roller 6 rolls and connects to the ground, which can help workers move the concrete block 3 to the construction site, thereby reducing the difficulty of transporting the concrete block 3 and reducing the workload of workers.

[0040] like Figure 2 and Figure 4 As shown, slots 8 are respectively provided at both ends of the top sidewall of the concrete pier 3. The slots 8 extend vertically, and the column 1 can be inserted vertically into the slot 8. The top sidewall of the concrete pier 3 is provided with a insertion groove 9, which is located between the two slots 8. The insertion groove 9 extends vertically, and the bottom end of the enclosure 2 can be inserted vertically into the insertion groove 9. The two ends of the insertion groove 9 are respectively connected to the left and right slots 8. Sliding grooves 35 are provided on the opposite sidewalls of the two adjacent columns 1. The sliding grooves 35 are connected to the insertion grooves 9. The sliding grooves 35 extend vertically, and the sidewall of the enclosure 2 can be slidably connected to the inner wall of the sliding groove 35 in the vertical direction.

[0041] like Figure 2 and Figure 4As shown, after the workers transport the pillars 1, the fence panels 2, and the concrete blocks 3 to the construction site, they first place the concrete blocks 3 in the appropriate positions. Then, they insert the pillars 1 into the slots 8 on the concrete blocks 3. After the pillars 1 are inserted into both ends of the concrete blocks 3, the workers align the bottom sidewall of the fence panel 2 with the corresponding sliding grooves 35 of the two adjacent pillars 1. Then, they push the fence panel 2 downwards into the sliding grooves 35 and the insertion slots 9. Finally, the workers fix the lighting lamps 34 to the top sidewall of the pillars 1 with bolts. The base of the lighting lamps 34 can abut against the fence panel 2 in the sliding grooves 35, thereby reducing the possibility of the fence panel 2 separating from the pillars 1. Thus, the workers complete the fence assembly work, which can separate the construction environment from the living environment.

[0042] like Figure 3 As shown, the inner walls of the slot 8 are provided with fixing grooves 10, which extend horizontally. The fixing grooves 10 are provided with fixing blocks 11 and first springs 12. The fixing blocks 11 are rectangular and are slidably connected to the inner wall of the fixing grooves 10 in the horizontal direction. The first springs 12 are horizontally arranged and their two ends are fixedly welded to the fixing blocks 11 and the inner walls of the fixing grooves 10, respectively. The side wall of the column 1 is provided with a limiting groove 13 for the fixing blocks 11 to be inserted. The slot 8 is provided with a limiting component 14 for limiting the fixing blocks 11.

[0043] like Figure 3 As shown, the limiting component 14 includes a stop plate 15 and a second spring 16. The stop plate 15 is rectangular and is slidably connected to the inner wall of the slot 8 in the vertical direction. The second spring 16 is arranged in the vertical direction. The bottom end of the second spring 16 is fixedly welded to the inner wall of the bottom end of the slot 8, and the top end of the second spring 16 is fixedly welded to the bottom side wall of the stop plate 15. The left and right side walls of the stop plate 15 can respectively abut against the fixing blocks 11 in the two relatively fixed slots 10. The bottom side wall of the column 1 can abut against the top side wall of the stop plate 15.

[0044] like Figure 3 As shown, a tie rod 26 is fixedly welded to the top side wall of the fixing block 11. The tie rod 26 is cylindrical. A groove 27 is provided on the top side wall of the concrete pier 3. The groove 27 extends vertically, and the tie rod 26 is slidably connected to the inner wall of the groove 27 in the horizontal direction.

[0045] like Figure 2 and Figure 3As shown, before the worker inserts the column 1 into the slot 8, the second spring 16 is in its natural state, and the side walls at both ends of the abutment plate 15 abut against the fixing block 11 in the fixing slot 10, causing the fixing block 11 to be in the fixing slot 10 and compressing the first spring 12. When the worker inserts the column 1 into the slot 8, the column 1 first abuts against the abutment plate 15. As the worker continues to push the column 1 downwards, the column 1 pushes the abutment plate 15 to compress the second spring 16, causing the abutment plate 15 to move away from the fixing block 11, thereby releasing the limiting position of the fixing block 11. However, at the same time, under the action of the side wall of the column 1, the fixing block 11 is still in the fixing groove 10, compressing the second spring 16, and the side wall of the fixing block 11 is slidably connected to the side wall of the column 1. When the column 1 is pushed by the worker to push the abutment plate 15 to compress the second spring 16 to the bottom of the slot 8, at this time, the fixing block 11 is aligned with the limiting groove 13 on the side wall of the column 1. The fixing blocks 11 on the opposite side wall of the slot 8 are respectively inserted into the limiting groove 13 on the opposite side wall of the column 1 under the elastic force of the first spring 12, thereby reducing the possibility of the column 1 separating from the concrete pier 3.

[0046] like Figure 2 and Figure 3 As shown, when the construction site is completed and the workers need to remove the fence, firstly, the workers remove the lighting 34. Then, the workers remove the fence panel 2 from the insertion slot 9 and the sliding slot 35. After that, the workers simultaneously pull the pull rods 26 on both sides of the column 1 and pull them away from the column 1. The pull rods 26 move horizontally in the sliding slot 27. The movement of the pull rods 26 causes the fixing block 11 to compress the second spring 16 and slide horizontally into the fixing slot 10. When the fixing block 11 moves away from the limiting slot 13, the abutment 15 moves upward under the elastic force of the second spring 16. The column 1 moves upward under the push of the abutment 15. At this time, the fixing block 11 is blocked by the abutment 15 in the fixing slot 10, compressing the first spring 12, which makes it easier for the workers to remove the column 1.

[0047] like Figure 3As shown, the fixing component is a support block 17, which is rectangular in shape. The support block 17 slides horizontally along the inner wall of the storage tank 7. A support groove 18 is provided on the side wall of the support rod 5 for the support block 17 to insert into. The support groove 18 extends horizontally. A drive assembly 19 for moving the support block 17 is provided inside the storage tank 7. A connecting groove 20 is provided on the bottom inner wall of the slot 8, extending vertically and communicating with the storage tank 7. The moving component 19 includes a connecting rod 21 and two hinged rods 22. Both the connecting rod 21 and the hinged rods 22 are cuboid in shape. The two hinged rods 22 are arranged one-to-one with the two support blocks 17. The top end of the connecting rod 21 is fixedly welded to the bottom side wall of the abutment plate 15. The connecting rod 21 is slidably connected to the inner wall of the connecting groove 20 in the vertical direction. The bottom end of the connecting rod 21 slides in the storage groove 7. The two ends of the hinged rods 22 are respectively hinged to the bottom side wall of the connecting rod 21 and the side wall of the support block 17.

[0048] like Figure 3 As shown, a third spring 23 is installed in the storage tank 4. The third spring 23 is installed vertically, and its top end is fixedly welded to the top inner wall of the storage tank 4. The bottom end of the third spring 23 is fixedly welded to the top side wall of the support rod 5. Two connecting blocks 24 are fixedly welded to the top inner wall of the storage tank 7. The two connecting blocks 24 are arranged in a one-to-one correspondence with the two support blocks 17. A fourth spring 25 is installed between the connecting blocks 24 and the support blocks 17. The fourth spring 25 is installed horizontally. One end of the fourth spring 25 is fixedly welded to the side wall of the support block 17, and the other end of the fourth spring 25 is fixedly welded to the connecting block 24. The fourth spring 25 is in a compressed state.

[0049] like Figure 2 and Figure 3 As shown, when workers push the concrete end for transport, the support block 17 is inserted into the support groove 18, fixing the position of the support rod 5, allowing the roller 6 to extend out of the storage groove 4 and abut against the ground to support the concrete pier 3, thereby the roller 6 drives the concrete pier 3 to move; after the workers push the concrete pier 3 to a suitable position on the construction site, when the workers insert the column 1 into the slot 8, the abutment plate 15 is pushed downward, the abutment plate 15 moves downward, the connecting rod 21 moves downward, the connecting rod 21 moves downward, the hinge rod 22 moves downward, the hinge rod 22 moves downward, and the support block 17 moves towards the horizontal compression of the fourth spring 25, thereby driving the support block 17 away from the support groove 18; after the support block 17 is disengaged from the support groove 18, the concrete pier 3 moves downward under its own weight until the bottom side wall of the concrete pier 3 is completely abutted against the ground; at this time, the roller 6 is in the storage groove 4, and the support rod 5 compresses the third spring 23, thereby reducing the possibility of the concrete pier 3 moving, and thus reducing the possibility of the fence collapsing.

[0050] like Figure 2 and Figure 3 As shown, after the construction is completed, the workers dismantle the fence and need to move the pillar 1, fence panel 2, and concrete block 3 onto the transport vehicle. At this time, the workers need to release the roller 6 out of the storage slot 4 and push the concrete block 3 to move. First, the workers need to take the pillar 1 out of the slot 8. After the pillar 1 is taken out, the abutment plate 15 moves upward under the force of the second spring 16, thereby driving the connecting rod 21 to move upward. The upward movement of the connecting rod 21 drives the hinge rod 22 to move upward, thereby driving the support block 17 to move closer to the support rod 5. At the same time, the force of the fourth spring 25 pushes the support block 17 to abut against the side wall of the support rod 5. Then, the workers lift one side of the concrete block 3. When the concrete block 3 is lifted, one end is briefly lifted off the ground. At this time, the support rod 5 moves downward under the force of the third spring 23. The movement of the support rod 5 can push the roller 6 outside the storage groove 4. During the downward movement of the support rod 5, the side wall of the support rod 5 is slidably connected to the support block 17. When the support groove 18 on the side wall of the support rod 5 is aligned with the support block 17, the support block 17 is inserted into the support groove 18 under the force of the fourth spring 25, thereby fixing the position of the support rod 5. When the worker lowers the concrete block 3, the roller 6 is outside the storage groove 4 and in contact with the ground. Similarly, when the worker lifts the other end of the concrete block 3, the rollers 6 at both ends are in contact with the ground, which makes it easier for the worker to move the concrete.

[0051] like Figure 4 As shown, a placement groove 28 is provided on the inner wall of the insertion groove 9. The placement groove 28 extends horizontally, and a placement plate 29 is slidably connected to the inner wall of the placement groove 28 in the horizontal direction. The placement plate 29 is cuboid in shape, and an inclined surface is provided on the side of the placement plate 29 near the enclosure plate 2. The bottom of the enclosure plate 2 can abut against the placement plate 29. Blocking grooves 37 are provided on the opposite inner walls of the left and right ends of the placement groove 28 in the horizontal direction. Blocking components 36 are provided in the blocking grooves 37 to prevent the placement plate 29 from detaching from the concrete pier 3. The blocking components 36 include abutment blocks 33. The fifth spring 31 is horizontally set, and its two ends are fixedly welded to the left inner wall of the blocking groove 37 and the left side wall of the abutment block 33, respectively. The abutment block 33 is composed of a square block and a ball block. The abutment block 33 is slidably connected to the inner wall of the blocking groove 37 in the horizontal direction and abuts against the placement plate 29. The two side walls of the placement plate 29 near the enclosure plate 2 are fixedly welded with a stop block 30, which is rectangular in shape. The stop block 30 can be slidably connected to the inner wall of the placement groove 28 in the horizontal direction and abuts against the abutment block 33.

[0052] like Figure 4As shown, before the enclosure panel 2 is inserted into the insertion slot 9, the placement plate 29 is completely within the placement slot 28, and the abutment block 33 abuts against one side wall of the placement slot 28, thereby reducing the possibility of the placement plate 29 sliding out of the placement slot 28. When the worker inserts the enclosure panel 2 into the insertion slot 9, the enclosure panel 2 abuts against the placement plate 29 via the inclined surface of the placement plate 29, pushing the placement plate 29 to move along the placement slot 28. During this movement, the side wall of the placement plate 29 abuts against the abutment block 33 via the spherical surface, pushing the abutment block 33 to compress the fifth spring 31 and move into the blocking slot 37. Subsequently, the placement slot 28 is drawn at one end of the placement plate 29, allowing workers to place the plate according to their needs. The size of the object determines the area exposed by the stretched placement plate 29. When the placement plate 29 is stretched to its maximum area, the stop block 30 abuts against the cube portion of the stop block 33, thereby reducing the possibility of the placement plate 29 detaching from the placement groove 28. After the workers remove the enclosure plate 2, they push the placement plate 29 into the placement groove 28. The stop block 33 slides against the side wall of the placement plate 29. When the placement plate 29 is completely inside the placement groove 28, the side wall of the placement plate 29 moves away from the stop block 33. The stop block 33 moves out of the blocking groove 37 under the elastic force of the fifth spring 31 and abuts against the placement plate 29, thereby reducing the possibility of the placement plate 29 appearing outside the placement groove 28 during the transportation of the concrete pier 3.

[0053] The implementation principle of this application embodiment is as follows: When the worker inserts the column 1 into the slot 8, the column 1 pushes the abutment plate 15 downward. The movement of the abutment plate 15 causes the connecting rod 21 to move downward. The movement of the connecting rod 21 causes the hinge rod 22 to move. The movement of the hinge rod 22 can drive the support block 17 to compress the fourth spring 25 and move away from the support groove 18, thereby releasing the fixing effect of the support rod 5. The concrete pier 3 moves downward under its own weight, so that the concrete pier 3 can abut against the ground and is not easy to move under its own weight. At this time, the roller 6 is completely in the storage groove 4, and the support rod 5 compresses the third spring 23. After the construction is completed, the worker removes the fence. When the worker takes the column 1 out of the slot 8, the abutment plate 15 moves upward under the push of the second spring 16. The upward movement of the abutment plate 15 can drive the connecting rod 21 to move upward, and the upward movement of the connecting rod can drive the hinge rod 22 to move upward. 22 moves upward, thereby driving the support block 17 to move closer to the support rod 5. The workers briefly lift both ends of the concrete block 3. When one end of the concrete block 3 is lifted, the concrete block 3 moves away from the ground support, and the support rod 5 moves downward under the elastic force of the third spring 23. The downward movement of the support rod 5 puts the roller 6 outside the storage groove 4. During the downward movement of the support rod 5, the side wall of the support rod 5 is slidably connected to the support block 17. When the support groove 18 on the support rod 5 is directly opposite the support block 17, the support block 17 is pushed into the support groove 18 by the elastic force of the fourth spring 25, thereby fixing the position of the support rod 5. When the workers put down the concrete block 3, the roller 6 is outside the storage groove 4 and contacts the ground to support the weight of the concrete block 3. Thus, the workers can push the concrete block 3 to move, thereby reducing the difficulty of transporting the concrete block 3 and reducing the workload of the workers.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
