Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a building hoisting platform. Background Art

[0002] With the development of cities, many high-rise buildings have been built. After the framework construction of a high-rise building is completed, it is necessary to transport steel bars, cement, bricks, cables, pipes, plates and construction equipment to each floor to carry out the next construction process of the building. The tower crane is used to hoist materials and equipment, and directly hoist them from the outside of the high-rise building to the corresponding floor, which improves the efficiency of construction. Since each floor has a lower floor and an upper floor, it is necessary to build a hoisting platform on each floor. The tower crane hoists the materials and equipment onto the hoisting platform, and the construction workers then move the materials and equipment from the hoisting platform to the indoor. The existing hoisting platform uses two main beams as the conveying track. The main beam is pressed on the upper surface of the floor through the support rod, and then the main beam extends out of the building. The two main beams serve as the track of the transport vehicle, so that the transport vehicle can be transported back and forth between the outdoors and indoors, which improves the unloading efficiency of the tower crane.

[0003] However, the existing support rods are supported on the lower surface of the upper floor through the upper end, and the lower end presses the main beam on the upper surface of the floor, so that the main beam will not overturn due to the load of the front section extending out of the building. However, the height of each floor has a certain deviation, and the support rods of fixed length cannot play an effective supporting role. Moreover, the support rods are installed on the main beams, which is not convenient for installation, disassembly and storage, and the transportation cost is high. There are also certain safety hazards in supporting by slender support rods, and there is no earthquake resistance. Since the support feet at the upper end of the support rods are fixed, there is a situation where the upper end of the support rods and the lower surface of the upper floor cannot be completely fitted to bear the force. The main beam lacks corresponding structures to ensure the limit in terms of forward and backward movement, and there is no corresponding connection between the main beams, and there is no insurance structure to prevent overturning. For some long strips of materials, such as bundled aluminum bars, wood, etc., the mobile trolley obviously has insufficient carrying space, making it inconvenient to transport the materials. There is no corresponding limit structure in the process of the trolley moving forward and backward to prevent the trolley from detaching from the main beam. Summary of the invention

[0004] The purpose of the present invention is to provide a construction hoisting platform to solve the problems of the existing construction hoisting platform, such as the inability to adjust the support rods, the inconvenience of adjustment, the lack of earthquake resistance, the poor stability and reliability, the low safety factor, and the insufficient bearing space of the mobile trolley structure. To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A building hoisting platform comprises two support assemblies 1 and a vehicle body 21; the support assembly 1 comprises a main beam 2, at least one telescopic rod 3 and auxiliary rods 4 corresponding to the telescopic rods 3; the lower end of the telescopic rod 3 is hinged to the rear section of the main beam 2, and the upper end of the telescopic rod 3 is supported on the lower surface of the upper floor slab, so that the rear section of the main beam 2 is pressed down on the upper surface of the lower floor slab; the front section of the main beam 2 extends to the outdoors; one end of the auxiliary rod 4 is detachably hinged to the telescopic rod 3, and the other end is detachably hinged to the main beam 2, so that the telescopic rod 3, the main beam 2 and the auxiliary rod 4 surround a triangle; guide grooves 22 are provided on the opposite inner sides of the main beams 2 of the two support assemblies 1; the vehicle body 21 comprises four bottom wheels 26; the bottom wheels 26 fit in the guide grooves 22 on the inner side of the main beam 2. It can be seen from the above structure that each main beam 2 cooperates with two bottom wheels 26 on the same side; one end of the auxiliary rod 4 is detachably hinged to the telescopic rod 3, and the other end is detachably hinged to the main beam 2. Since both ends of the main beam 2 and the auxiliary rod 4 are constrained, the hinged structure can no longer rotate. The telescopic rod 3, the main beam 2 and the auxiliary rod 4 form a triangle, which is stable enough to improve the stability of the telescopic rod. The vehicle body 21 moves along the main beam 2 to the front section of the main beam 2, and the material is hoisted onto the vehicle body 21; then the motor drives the bottom wheel 26 to rotate, and the vehicle body 21 moves along the main beam 2 to the indoor unloading.

[0006] Furthermore, the vehicle body 21 also includes a bottom plate 23, a front baffle 24 and two side plates 25; four bottom wheels 26 are provided below the bottom plate 23 to drive the bottom plate 23 to move; side plates 25 are fixed on both sides above the bottom plate 23, and the front end of the bottom plate 23 is hinged at the lower end of the front baffle 24; the front baffle 24 has a closed state with a vertical angle to the bottom plate 23 and an open state with the bottom plate 23 in the same plane. It can be seen from the above structure that when the tower crane is hoisting ordinary materials, the vehicle body 21 moves along the main beam 2 to the front section of the main beam 2, and the materials are hoisted onto the bottom plate 23; the front baffle 24 and the bottom plate 23 are in a closed state with a vertical angle, so that the materials are shielded in the front, left and right directions and will not fall, and then the motor drives the bottom wheels 26 to rotate, and the vehicle body 21 moves along the main beam 2 to the indoor unloading. When the tower crane is hoisting long strips of materials, the front baffle 24 and the bottom plate 23 are in an open state on the same plane, which expands the support area of ​​the bottom plate 23, so that the vehicle body 21 can conveniently transport the long strips of materials and deliver the long strips of materials to the room.

[0007] Furthermore, when the front door 24 is in a closed state, the front door 24 and the two side panels 25 are fixed; a first stopper 27 is provided on both sides of the front end of the bottom plate 23; when the front door 24 is in an open state, the front door 24 and the two first stoppers 27 are fixed. As can be seen from the above structure, when the front door 24 is in a closed state, it can be fixed by a conventional bolt detachable structure and the two side panels 25 to keep the front door 24 and the bottom plate 23 at a vertical angle. When the front door 24 is in an open state, it can be fixed by a conventional bolt detachable structure and the two first stoppers 27 to keep the front door 24 and the bottom plate 23 in the same plane.

[0008] Furthermore, a vertical plate 28 is hinged at the upper end of the front baffle 24; the vertical plate 28 has a non-working state in which it is in contact with the inner side of the front baffle 24 and a working state in which it is at a vertical angle to the front baffle 24; when the vertical plate 28 is in the non-working state, the vertical plate 28 and the front baffle 24 are fixed; a second stopper 29 is provided on each side of the upper end of the front baffle 24; when the vertical plate 28 is in the working state, the vertical plate 28 and the two second stoppers 29 are fixed. It can be seen from the above structure that when the tower crane is hoisting ordinary materials, the vertical plate 28 is in a non-working state in which it is in contact with the inner side of the front baffle 24. When the tower crane is hoisting long strip materials, the vertical plate 28 and the front baffle 24 are in a working state in which they are at a vertical angle. At this time, the front baffle 24 and the bottom plate 23 are in an open state in the same plane, which expands the support area of ​​the bottom plate 23, and the vertical plate 28 blocks the front of the long strip materials to prevent the long strip materials from falling from the front. When the vertical plate 28 is in a non-working state, it can be fixed to the front door 24 by a conventional detachable bolt structure to keep the vertical plate 28 and the front door 24 in close contact. When the vertical plate 28 is in a working state, it can be fixed to the front door 24 by a conventional detachable bolt structure and two second stoppers 29 to keep the vertical plate 28 and the front door 24 at a vertical angle.

[0009] Furthermore, a locking plate 41 is provided on each side of the bottom plate 23; a locking hole 42 is provided on the locking plate 41; a matching hole 43 is provided on the main beam 2; when the vehicle body 21 moves to the rear end along the main beam 2, the locking hole 42 and the matching hole 43 are aligned; locking pins are inserted into the locking hole 42 and the matching hole 43; a limiting portion 44 is provided at the front end of the main beam 2; the limiting portion 44 is used to limit the bottom wheel 26 from sliding out of the guide groove 22; and a plurality of reinforcing rods 45 are welded between the two main beams 2. As can be seen from the above structure, when the vehicle body 21 moves to the rear end along the main beam 2, the locking hole 42 and the matching hole 43 are aligned; the locking pin passes through the locking hole 42 and the matching hole 43, so that the vehicle body 21 can be locked when not working, or locked when unloading, to prevent the vehicle body 21 from moving at will. The limiting portion 44 is used to limit the bottom wheel 26 from sliding out of the guide groove 22 to ensure safe operation. The reinforcing rod 45 makes the two main beams 2 more stable and reliable.

[0010] Furthermore, a rotating shaft 5 corresponding to the telescopic rod 3 is fixed on the outer wall of the rear section of the main beam 2; the lower end of the telescopic rod 3 is rotatably connected to the rotating shaft 5; when the auxiliary rod 4 is disassembled, the telescopic rod 3 is rotated to be parallel to the main beam 2 and stored on one side of the rear section of the main beam 2; the rear section of the main beam 2 is hinged with two telescopic rods 3; the two telescopic rods 3 are staggered when they are rotated to be parallel to the main beam 2. It can be seen from the above structure that when transportation is required, the auxiliary rod 4 is disassembled. The telescopic rod can rotate around the rotating shaft 5 and be stored on one side of the rear section of the main beam 2. The entire device is easy to transport and saves space. The rear section of each main beam 2 is hinged with two telescopic rods 3, so the two support assemblies 1 have four telescopic rods 3 for stable support. The two telescopic rods 3 are located at a front and rear position of the rear section of the main beam 2. The front telescopic rod 3 flips backward, and the rear telescopic rod 3 flips forward. When the two telescopic rods 3 are rotated to be parallel to the main beam 2, they are staggered, so all the telescopic rods 3 can be stored on one side of the rear section of the main beam 2, which is convenient for storage and transportation.

[0011] Furthermore, the front end of the lower floor slab is provided with an upper retaining wall 6 and a lower retaining wall 7; the upper retaining wall 6 is provided with a discharge notch 8; the main beams 2 of the two support assemblies 1 are attached to both sides of the discharge notch 8; a baffle 9 is provided on the outer side wall of the rear section of the main beam 2; the baffle 9 is attached to the inner side of the upper retaining wall 6. As can be seen from the above structure, the discharge notch 8 is convenient for the vehicle body 21 to enter and exit. A baffle 9 is provided on the outer side wall of the rear section of the main beam 2; the baffle 9 is attached to the inner side of the upper retaining wall 6; in this way, the main beam 2 will not move forward and fall outdoors due to the limitation of the baffle 9.

[0012] Furthermore, two support assemblies 1 are also provided on the upper floor; a turnbuckle adjustment rod 10 is connected between the front section of the main beam 2 of the support assembly 1 of the upper floor and the front section of the main beam 2 of the support assembly 1 corresponding to the lower floor; the two ends of the turnbuckle adjustment rod 10 are hinged to the front section of the corresponding main beam 2; the turnbuckle adjustment rod 10 is against the outer side of the lower retaining wall 7 provided at the front end of the upper floor. As can be seen from the above structure, the upper floor also has the same support structure; a turnbuckle adjustment rod 10 is connected between the front section of the main beam 2 of the support assembly 1 of the upper floor and the front section of the main beam 2 of the support assembly 1 corresponding to the lower floor. The turnbuckle adjustment rod 10 connects the upper and lower main beams 2 by adjusting the length, and can transmit tension and pressure to each other. In this way, if the force on one main beam 2 is unbalanced, the other main beam 2 will assist in playing a role of insurance. This mutually linked structure ensures the safety and reliability of each main beam 2. When the main beam 2 is subjected to a force moving indoors, the turnbuckle adjustment rod 10 plays a role of limiting and hindering, ensuring that the main beam 2 will not move backwards.

[0013] Furthermore, the telescopic rod 3 comprises a cylinder 31, a rod 32 and a nut sleeve 33; the cylinder 31 is inserted with the rod 32 which moves up and down along the cylinder 31; the rod 32 is provided with an upper boss 34 and a lower boss 35 on the part of the rod 32 in the cylinder 31; the cylinder 31 is provided with a vertical slot 36 which penetrates the cylinder 31; the upper boss 34 and the lower boss 35 extend out of the vertical slot 36; the nut sleeve 33 is connected to the outer surface of the cylinder 31 by threading; the nut sleeve 33 is located between the upper boss 34 and the lower boss 35; the upper end of the rod 32 is hinged with a support foot 37; the support foot 37 is provided with a rubber foot pad 38; the lower surface of the main beam 2 is provided with a buffer pad. As can be seen from the above structure, the rod 32 can move up and down in the cylinder 31, so that the rod 32 and the cylinder 31 are extended or shortened as a whole. The upper part of the rod body 32 extends out of the cylinder body 31, and the lower part is wrapped in the cylinder body 31; the part of the rod body 32 in the cylinder body 31 is provided with an upper boss 34 and a lower boss 35, the upper boss 34 is higher than the lower boss 35, the upper boss 34 and the lower boss 35 are located on the same side, and the cylinder body 31 at this side is provided with a vertical slit 36 ​​that penetrates the cylinder body 31, so that the upper boss 34 and the lower boss 35 can extend out from the vertical slit 36; the outer surface of the cylinder body 31 is threaded, and the nut sleeve 33 is connected to the outer surface of the cylinder body 31 through threads, and the nut sleeve 33 is located between the upper boss 34 and the lower boss 35. Therefore, when the nut sleeve 33 rotates and moves upward, it will push the upper boss 34 to drive the rod body 32 to extend out of the cylinder body 31 until the upper end of the rod body 32 hits the lower surface of the upper floor. When the nut sleeve 33 rotates and moves downward, it will push the lower boss 35 to drive the rod body 32 to hide in the cylinder 31, making the entire telescopic rod shorter and convenient for storage and transportation. The telescopic rod is adjustable in length, so that when the floor height changes, the telescopic rod can also fully play a supporting role and press the main beam 2 on the upper surface of the lower floor. The telescopic rod of the present invention can adjust the length of the telescopic rod by directly rotating the nut sleeve 33, which is very convenient to adjust. The number of the upper boss 34, the lower boss 35 and the vertical seam 36 is two, and the two upper bosses 34, the two lower bosses 35 and the two vertical seams 36 are symmetrical to each other. Each vertical seam 36 corresponds to an upper boss 34 and a lower boss 35; in this way, the nut sleeve 33 simultaneously pushes two symmetrical upper bosses 34 or lower bosses 35 to drive the rod body 32 to move up and down. The existing support foot 37 is fixed to the upper end of the rod body 32, so when the plane of the support foot 37 is not completely parallel to the lower surface of the upper floor, the support foot 37 cannot be pressed on the lower surface of the upper floor with its entire plane, resulting in a lack of effective support. The support foot 37 is hinged to the upper end of the rod body 32, and the support foot 37 can adjust the angle of the support foot 37 according to the lower surface of the upper floor, so that the support foot 37 and the lower surface of the upper floor are completely in contact, so that the telescopic rod can play an effective support. When the telescopic rod is vibrated, the rubber foot pad 38 plays a buffering role, so that the telescopic rod has earthquake resistance and improves stability. The buffer pad can buffer the vibration of the main beam 2 and improve the earthquake resistance.

[0014] Furthermore, two handles 39 are provided on the outer wall of the nut sleeve 33; the part of the nut sleeve 33 below the handle 39 is hexagonal; one end of the auxiliary rod 4 is detachably hinged on the barrel 31 of the telescopic rod 3. It can be seen from the above structure that when the nut sleeve 33 is subjected to less force, the nut sleeve 33 can be directly rotated by holding the handle 39 to make the nut sleeve 33 rotate quickly, thereby improving the adjustment efficiency. When the nut sleeve 33 cannot be rotated by manpower, the hexagonal part of the nut sleeve 33 below the handle 39 can be used with a wrench to assist in the rotation, saving physical effort. The barrel 31, the main beam 2 and the auxiliary rod 4 form a triangle, which is stable enough to improve the stability of the telescopic rod.

[0015] The beneficial effects of the present invention are:

[0016] The present invention discloses a construction hoisting platform, which belongs to the field of construction technology, and includes two support assemblies and a vehicle body; the support assembly includes a main beam, at least one telescopic rod and an auxiliary rod corresponding to the telescopic rod; the lower end of the telescopic rod is hinged to the rear section of the main beam, and the upper end of the telescopic rod is supported on the lower surface of the upper floor, so that the rear section of the main beam is pressed down on the upper surface of the lower floor; the front section of the main beam extends to the outdoors; one end of the auxiliary rod is detachably hinged to the telescopic rod, and the other end is detachably hinged to the main beam, so that the telescopic rod, the main beam and the auxiliary rod form a triangle; the inner sides of the main beams of the two support assemblies are provided with guide grooves; the vehicle body includes four bottom wheels; the bottom wheels are fitted in the guide grooves on the inner side of the main beam.

Since both ends of the main beam 2 and the auxiliary rod 4 are constrained, the hinged structure can no longer rotate.

When the front door 24 is in an open state, it can be fixed by a conventional bolt detachable structure and the two first stoppers 27 to keep the front door 24 and the bottom plate 23 in the same plane.

[0033] The upper end of the front baffle 24 is hinged with a vertical plate 28; the vertical plate 28 has a non-working state in contact with the inner side of the front baffle 24 and a working state in which the vertical plate 28 is at a vertical angle to the front baffle 24; when the vertical plate 28 is in the non-working state, the vertical plate 28 and the front baffle 24 are fixed; a second stopper 29 is provided on each side of the upper end of the front baffle 24; when the vertical plate 28 is in the working state, the vertical plate 28 and the two second stoppers 29 are fixed. It can be seen from the above structure that when the tower crane is hoisting ordinary materials, the vertical plate 28 is in a non-working state in contact with the inner side of the front baffle 24. When the tower crane is hoisting long strip materials, the vertical plate 28 and the front baffle 24 are in a working state in which the vertical plate 28 is at a vertical angle. At this time, the front baffle 24 and the bottom plate 23 are in an open state in the same plane, which expands the support area of ​​the bottom plate 23, and the vertical plate 28 blocks the front of the long strip materials to prevent the long strip materials from falling from the front. When the vertical plate 28 is in a non-working state, it can be fixed to the front door 24 by a conventional detachable bolt structure to keep the vertical plate 28 and the front door 24 in close contact. When the vertical plate 28 is in a working state, it can be fixed to the front door 24 by a conventional detachable bolt structure and two second stoppers 29 to keep the vertical plate 28 and the front door 24 at a vertical angle.

[0034] A locking plate 41 is provided on each side of the bottom plate 23; a locking hole 42 is provided on the locking plate 41; a matching hole 43 is provided on the main beam 2; when the vehicle body 21 moves to the rear end along the main beam 2, the locking hole 42 and the matching hole 43 are aligned; locking pins are inserted into the locking hole 42 and the matching hole 43; a limiting portion 44 is provided at the front end of the main beam 2; the limiting portion 44 is used to limit the bottom wheel 26 from sliding out of the guide groove 22; and a plurality of reinforcing rods 45 are welded between the two main beams 2. As can be seen from the above structure, when the vehicle body 21 moves to the rear end along the main beam 2, the locking hole 42 and the matching hole 43 are aligned; the locking pin passes through the locking hole 42 and the matching hole 43, so that the vehicle body 21 can be locked when not working, or locked when unloading, to prevent the vehicle body 21 from moving at will. The limiting portion 44 is used to limit the bottom wheel 26 from sliding out of the guide groove 22 to ensure safe operation. The reinforcing rod 45 makes the two main beams 2 more stable and reliable.

[0035] A rotating shaft 5 corresponding to the telescopic rod 3 is fixed on the outer wall of the rear section of the main beam 2; the lower end of the telescopic rod 3 is rotatably connected to the rotating shaft 5; when the auxiliary rod 4 is disassembled, the telescopic rod 3 is rotated to be parallel to the main beam 2 and stored on one side of the rear section of the main beam 2; the rear section of the main beam 2 is hinged with two telescopic rods 3; the two telescopic rods 3 are staggered when they are rotated to be parallel to the main beam 2. It can be seen from the above structure that when transportation is required, the auxiliary rod 4 is disassembled. The telescopic rod can rotate around the rotating shaft 5 and be stored on one side of the rear section of the main beam 2. The whole device is easy to transport and saves space. The rear section of each main beam 2 is hinged with two telescopic rods 3, so the two support assemblies 1 have four telescopic rods 3 for stable support. The two telescopic rods 3 are located at a front and rear position of the rear section of the main beam 2. The front telescopic rod 3 flips backward, and the rear telescopic rod 3 flips forward. When the two telescopic rods 3 are rotated to be parallel to the main beam 2, they are staggered, so all the telescopic rods 3 can be stored on one side of the rear section of the main beam 2, which is convenient for storage and transportation.

[0036] The front end of the lower floor slab is provided with an upper retaining wall 6 and a lower retaining wall 7; the upper retaining wall 6 is provided with a discharge notch 8; the main beams 2 of the two support assemblies 1 are attached to both sides of the discharge notch 8; a baffle 9 is provided on the outer side wall of the rear section of the main beam 2; the baffle 9 is attached to the inner side of the upper retaining wall 6. As can be seen from the above structure, the discharge notch 8 is convenient for the vehicle body 21 to enter and exit. A baffle 9 is provided on the outer side wall of the rear section of the main beam 2; the baffle 9 is attached to the inner side of the upper retaining wall 6; in this way, the main beam 2 will not move forward and fall outdoors due to the limitation of the baffle 9.

[0037] The upper floor is also provided with two support assemblies 1; a turnbuckle adjustment rod 10 is connected between the front section of the main beam 2 of the support assembly 1 of the upper floor and the front section of the main beam 2 of the support assembly 1 corresponding to the lower floor; the two ends of the turnbuckle adjustment rod 10 are hinged with the front section of the corresponding main beam 2; the turnbuckle adjustment rod 10 is against the outer side of the lower retaining wall 7 provided at the front end of the upper floor. As can be seen from the above structure, the upper floor also has the same support structure; a turnbuckle adjustment rod 10 is connected between the front section of the main beam 2 of the support assembly 1 of the upper floor and the front section of the main beam 2 of the support assembly 1 corresponding to the lower floor. The turnbuckle adjustment rod 10 connects the upper and lower main beams 2 by adjusting the length, and can transmit tension and pressure to each other. In this way, if the force on one main beam 2 is unbalanced, the other main beam 2 will assist in playing a role of insurance. This mutually linked structure ensures the safety and reliability of each main beam 2. When the main beam 2 is subjected to a force moving indoors, the turnbuckle adjustment rod 10 plays a role of limiting and hindering, ensuring that the main beam 2 will not move backwards.

[0038] The telescopic rod 3 includes a cylinder 31, a rod 32 and a nut sleeve 33; the cylinder 31 is inserted with the rod 32 which moves up and down along the cylinder 31; the rod 32 is provided with an upper boss 34 and a lower boss 35 on the part of the cylinder 31; the cylinder 31 is provided with a vertical slit 36 ​​which penetrates the cylinder 31; the upper boss 34 and the lower boss 35 extend out of the vertical slit 36; the nut sleeve 33 is connected to the outer surface of the cylinder 31 by threading; the nut sleeve 33 is located between the upper boss 34 and the lower boss 35; the upper end of the rod 32 is hinged with a support foot 37; the support foot 37 is provided with a rubber foot pad 38; the lower surface of the main beam 2 is provided with a buffer pad. As can be seen from the above structure, the rod 32 can move up and down in the cylinder 31, so that the rod 32 and the cylinder 31 are extended or shortened as a whole. The upper part of the rod body 32 extends out of the cylinder body 31, and the lower part is wrapped in the cylinder body 31; the part of the rod body 32 in the cylinder body 31 is provided with an upper boss 34 and a lower boss 35, the upper boss 34 is higher than the lower boss 35, the upper boss 34 and the lower boss 35 are located on the same side, and the cylinder body 31 at this side is provided with a vertical slit 36 ​​that penetrates the cylinder body 31, so that the upper boss 34 and the lower boss 35 can extend out from the vertical slit 36; the outer surface of the cylinder body 31 is threaded, and the nut sleeve 33 is connected to the outer surface of the cylinder body 31 through threads, and the nut sleeve 33 is located between the upper boss 34 and the lower boss 35. Therefore, when the nut sleeve 33 rotates and moves upward, it will push the upper boss 34 to drive the rod body 32 to extend out of the cylinder body 31 until the upper end of the rod body 32 hits the lower surface of the upper floor. When the nut sleeve 33 rotates and moves downward, it will push the lower boss 35 to drive the rod body 32 to hide in the cylinder 31, making the entire telescopic rod shorter and convenient for storage and transportation. The telescopic rod is adjustable in length, so that when the floor height changes, the telescopic rod can also fully play a supporting role and press the main beam 2 on the upper surface of the lower floor. The telescopic rod of the present invention can adjust the length of the telescopic rod by directly rotating the nut sleeve 33, which is very convenient to adjust. The number of the upper boss 34, the lower boss 35 and the vertical seam 36 is two, and the two upper bosses 34, the two lower bosses 35 and the two vertical seams 36 are symmetrical to each other. Each vertical seam 36 corresponds to an upper boss 34 and a lower boss 35; in this way, the nut sleeve 33 simultaneously pushes two symmetrical upper bosses 34 or lower bosses 35 to drive the rod body 32 to move up and down. The existing support foot 37 is fixed to the upper end of the rod body 32, so when the plane of the support foot 37 is not completely parallel to the lower surface of the upper floor, the support foot 37 cannot be pressed on the lower surface of the upper floor with its entire plane, resulting in a lack of effective support. The support foot 37 is hinged to the upper end of the rod body 32, and the support foot 37 can adjust the angle of the support foot 37 according to the lower surface of the upper floor, so that the support foot 37 and the lower surface of the upper floor are completely in contact, so that the telescopic rod can play an effective support. When the telescopic rod is vibrated, the rubber foot pad 38 plays a buffering role, so that the telescopic rod has earthquake resistance and improves stability. The buffer pad can buffer the vibration of the main beam 2 and improve the earthquake resistance.

[0039] Two handles 39 are provided on the outer wall of the nut sleeve 33; the part of the nut sleeve 33 below the handle 39 is hexagonal; one end of the auxiliary rod 4 is detachably hinged on the barrel 31 of the telescopic rod 3. It can be seen from the above structure that when the nut sleeve 33 is subjected to less force, the nut sleeve 33 can be directly rotated by holding the handle 39 to make the nut sleeve 33 rotate quickly, thereby improving the adjustment efficiency. When the nut sleeve 33 cannot be rotated by human power, the hexagonal part of the nut sleeve 33 below the handle 39 can be used with a wrench to assist in the rotation, saving physical effort. The barrel 31, the main beam 2 and the auxiliary rod 4 form a triangle, which is stable enough to improve the stability of the telescopic rod.
