DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0035] As Figures 1-8 shown, the technical solutions adopted by the application are as follows: a construction platform for house building engineering, comprising a base 1, a mounting rod 7 and a storage plate 27.

[0036] The base 1 is provided with a plurality of wheels 2, so that the construction platform can be easily moved. The base 1 is provided with a first guide rail 4, and the platform plate 3 is slidably connected to the first guide rail 4. The base 1 is provided with a first lifting mechanism for driving the platform plate 3 to move up and down. The first lifting mechanism is a conventional technology and is not shown in the figure. For example, the first lifting mechanism can be a screw nut mechanism. The platform plate 3 is provided with a fence 5 around the upper end surface of the platform plate 3. The fence 5 is provided with a door 6, and the door 6 is provided with a lock catch. The fence 5 has a protection function, which can increase the safety factor when the worker is on the platform plate 3. The door 6 can facilitate the worker to get on and off the platform plate 3. The door 6 is prevented from being accidentally opened by the lock catch. The platform plate 3 is provided with a plurality of parallel receiving grooves 19, and the platform plate 3 is provided with a sliding groove 20.

[0037] The platform plate 3 is provided with a first transmission assembly. The first transmission assembly comprises an air bag 26, a gas channel 25, an elastic expansion air bag 24, and a pushing member. The platform plate 3 is provided with an installation cavity, and the installation cavity is in communication with the receiving groove 19 located in the middle. The elastic expansion air bag 24 is installed in the installation cavity, and the expansion direction of the elastic expansion air bag 24 is consistent with the length direction of the receiving groove 19. The air bag 26 is fixedly arranged at the bottom of one end of the platform plate 3. The gas channel 25 is located in the interior of the platform plate 3, and the elastic expansion air bag 24 and the air bag 26 are in communication through the gas channel 25. The pushing member is fixedly connected with the elastic expansion air bag 24.

[0038] The pushing member comprises a sliding block 21, a push rod 22, and a connecting rod 23. The push rod 22 and the sliding block 21 are provided in plurality, and the push rod 22, the sliding block 21, and the receiving groove 19 are in one-to-one correspondence. The push rod 22 and the sliding block 21 are fixedly connected.

[0039] The plurality of sliding blocks 21 are fixedly arranged on the connecting rod 23 and are distributed along the length direction of the connecting rod 23. The connecting rod 23 is slidably connected with the sliding groove 20. The sliding block 21 located in the middle is fixedly connected with the elastic expansion air bag 24. When the air bag 26 is extruded, the gas in the air bag 26 enters the elastic expansion air bag 24 through the gas channel 25, so that the elastic expansion air bag 24 is elongated, and the elastic expansion air bag 24 pushes the sliding block 21 located in the middle to move along the length direction of the receiving groove 19. The sliding block 21 located in the middle pushes the plurality of sliding blocks 21 and the push rod 22 to move through the connecting rod 23, and then the push rod 22 moves along the corresponding receiving groove 19.

[0040] One end of the fence 5 is provided with a notch. The mounting rod 7 is arranged on the platform plate 3 near the end of the notch in a one-way rotation manner, and the axis of the mounting rod 7 is perpendicular to the length direction of the receiving groove 19. One end of the mounting rod 7 is coaxially fixedly connected with a shaft rod 15, and the shaft rod 15 is rotatably arranged on the platform plate 3 through a first one-way bearing 16. For example, Figure 1The shaft 15 can only rotate counterclockwise under the action of the first one-way bearing 16, i.e. the upper end of the mounting rod 7 can only move towards the inside of the platform plate 3. A plurality of first through holes 8 and a plurality of second through holes 9 are formed on the mounting rod 7 in the radial direction of the mounting rod 7, and the first through holes 8, the second through holes 9 and the receiving groove 19 correspond one by one, the axis of the first through hole 8 and the axis of the second through hole 9 are perpendicular to each other and in the same vertical plane.

[0041] A first barrier 11 is limitedly and slidably arranged in each first through hole 8. Limiting blocks 10 are fixedly arranged on the inner walls at both ends of the first through hole 8, each end of the first through hole 8 has two oppositely arranged limiting blocks 10, and the projections of the limiting blocks 10 at both ends on the cross section perpendicular to the axis of the first through hole 8 are uniformly distributed along the circumference. Two groups of first sliding grooves 12 are formed on the first barrier 11. Each group of first sliding grooves 12 includes two first sliding grooves 12, which are in one-to-one sliding fit with the limiting blocks 10. One end of the first sliding groove 12 is open, and the other end of the first sliding groove 12 is provided with a limiting portion, and the opening of the first sliding groove 12 and the corresponding limiting block 10 are located on the same side of the first through hole 8.

[0042] A second barrier 13 is limitedly and slidably arranged in each second through hole 9. Limiting blocks 10 are fixedly arranged on the inner walls at both ends of the second through hole 9, each end of the second through hole 9 has two oppositely arranged limiting blocks 10, and the projections of the limiting blocks 10 at both ends on the cross section perpendicular to the axis of the second through hole 9 are uniformly distributed along the circumference. Two groups of second sliding grooves 14 are formed on the second barrier 13, each group of second sliding grooves 14 includes two second sliding grooves 14. The second sliding grooves 14 are in one-to-one sliding fit with the limiting blocks 10 in the second through hole 9. One end of the second sliding groove 14 is open, and the other end is provided with a limiting portion, and the opening of the second sliding groove 14 and the corresponding limiting block 10 are located on the same side of the second through hole 9. In this way, the second barrier 13 can be prevented from coming out of the second through hole 9.

[0043] The shape and size of the push rod 22 are adapted to the first through hole 8 and the second through hole 9, so that the push rod 22 can enter the first through hole 8 and the second through hole 9.

[0044] It should be noted that the first barrier 11 and the second barrier 13 have the same structure, but different positions, and the state and position of the first barrier 11 and the second barrier 13 are mutually transformed. When the first barrier 11 is in the receiving groove 19, the second barrier 13 vertically upwards blocks the fence 5, and when the second barrier 13 is in the receiving groove 19, the first barrier 11 vertically upwards blocks the gap of the fence 5. And the first barrier 11 and the second barrier 13 are adapted to the receiving groove 19, i.e. the first barrier 11 and the second barrier 13 can be accommodated in the receiving groove 19.

[0045] The storage plate 27 is arranged on the base 1 and moves up and down, and the storage plate 27 is on the same side of the platform plate 3 as the mounting rod 7. The second guide rail 31 is fixedly arranged on the base 1, and the storage plate 27 is in sliding cooperation with the second guide rail 31. The second lifting mechanism for driving the storage plate 27 to move up and down is arranged on the base 1. The second lifting mechanism is a conventional prior art, which is not shown in the figure, such as a screw nut mechanism, a pulley elevator, etc.

[0046] A plurality of parallel through grooves 28 are arranged on the storage plate 27, and the through grooves 28 are open at one end close to the mounting rod 7, and the through grooves 28 correspond to the receiving grooves 19 one by one. When the storage plate 27 is lifted to a certain height, the receiving groove 19, the corresponding first through hole 8 or second through hole 9, and the corresponding through groove 28 are on the same straight line. The cross-sectional shape and size of the through groove 28 are adapted to the first rail 11 and the second rail 13, so that the first rail 11 and the second rail 13 can enter the through groove 28 and can be separated from above the through groove 28. The side of the storage plate 27 close to the mounting rod 7 has a fixed plate 29, and the fixed plate 29 cooperates with the air bag 26. The storage plate 27 drives the mounting rod 7 to rotate in one direction through the second transmission assembly.

[0047] The second transmission assembly includes a gear 17 and a rack 30. The shaft 15 penetrates the platform plate 3 at the end away from the mounting rod 7 to the outside of the platform plate 3, and the gear 17 is arranged on the end of the shaft 15 away from the mounting rod 7 through the second one-way bearing 18. The rack 30 is fixedly arranged on the fixed plate 29, and the rack 30 cooperates with the gear 17. The design of the rack 30 should cooperate with the gear 17, so that the rack 30 drives the gear 17 to rotate counterclockwise by 90 degrees during the descending process.

[0048] When the storage plate 27 moves upward, the rack 30 drives the gear 17 to rotate clockwise, the outer ring of the second one-way bearing 18 rotates clockwise relative to the inner ring of the second one-way bearing 18, the gear 17 rotates clockwise relative to the shaft 15, and the gear 17 cannot drive the shaft 15 to rotate clockwise through the second one-way bearing 18, that is, the mounting rod 7 is stationary. When the storage plate 27 moves downward, the storage plate 27 drives the gear 17 to rotate counterclockwise, and the gear 17 drives the shaft 15 to rotate counterclockwise through the second one-way bearing 18, thereby driving the mounting rod 7 to rotate counterclockwise.

[0049] When the storage plate 27 moves upward, the fixed plate 29 extrudes the air bag 26. The elastic expansion air bag 24 is elongated, thereby driving the push rod 22 to move along the receiving groove 19, and the push rod 22 pushes the corresponding first rail 11 in the receiving groove 19 to slide outward along the first through hole 8 and enter the corresponding through groove 28 and be below the materials on the storage plate 27.

[0050] Working principle: as Figure 2As shown, in the initial state, the first rail 11 in the horizontal state is in the storage slot 19, and the second rail 13 in the vertical upward state blocks the gap of the fence 5. The lower end of the second rail 13 abuts against the first rail 11, and the limiting part at the lower end of the second rail 13 cooperates with the limiting block 10 at the upper end of the second through hole 9, so that the second rail 13 cannot be moved upward any more. As shown, Figure 1 As shown in the direction, due to the action of the first one-way bearing 16, the shaft 15 can only rotate counterclockwise relative to the platform plate 3, thereby preventing the second rail 13 from rotating clockwise. Since the first rail 11 is limited by the storage slot 19, the mounting rod 7 cannot rotate counterclockwise in the initial state, so that the second rail 13 remains in the vertical upward state. The second rail 13 is in a relatively fixed state to ensure the safety of the personnel on the construction platform. The platform plate 3 is at the upper end of the first guide rail 4. The placement plate 27 is at the lower end of the second guide rail 31. The elastic expansion air bag 24 is in a natural state, i.e., a shortened state. The push rod 22 is at the left end of the storage slot 19, and the air bag 26 is filled with gas.

[0051] In use, the materials are placed on the placement plate 27, and then the placement plate 27 is raised. During the upward movement of the placement plate 27, the rack 30 gradually approaches and engages with the gear 17, and the rack 30 drives the gear 17 to rotate clockwise. Due to the action of the second one-way bearing 18, the shaft 15 and the mounting rod 7 are stationary. When the placement plate 27 is raised, the upper end surface of the fixed plate 29 gradually contacts the air bag 26.

[0052] With the rising of the fixed plate 29, the fixed plate 29 extrudes the air bag 26, so that the gas in the air bag 26 enters the elastic expansion air bag 24 through the gas passage 25, and the elastic expansion air bag 24 is elongated. The elastic expansion air bag 24 pushes the plurality of push rods 22 to move simultaneously through the connecting rod 23 and the sliding block 21. The sliding block 21 and the push rod 22 move along the corresponding storage slot 19 to the direction close to the mounting rod 7, and the connecting rod 23 moves along the sliding slot 20. The push rod 22 pushes the corresponding first rail 11 to move outward along the first through hole 8. When the left end of the first rail 11 enters the mounting rod 7, the push rod 22 extends into the first through hole 8 and continues to push the first rail 11 to move to the right until the left end of the first rail 11 passes the second rail 13. At this time, the limiting part at the left end of the first rail 11 abuts against the limiting block 10 at the right end of the first through hole 8. The through slot 28 is flush with the storage slot 19 at this time, the first rail 11 is located in the through slot 28, and the first rail 11 is below the materials.

[0053] Then the shelf 27 is moved downward, the materials on the shelf 27 are left on the first rail 11. With the descent of the shelf 27, the pressure of the fixing plate 29 on the air bag 26 is gradually reduced, the elastic expansion air bag 24 is gradually shortened under the action of the elastic potential energy of the elastic expansion air bag 24, and the gas in the elastic expansion air bag 24 gradually flows into the air bag 26. The elastic expansion air bag 24 drives the sliding block 21 and the push rod 22 to move away from the mounting rod 7 through the connecting rod 23. When the fixing plate 29 is separated from the air bag 26, the elastic expansion air bag 24 returns to the natural state. When the push rod 22 is separated from the corresponding first through hole 8, the second rail 13 is moved downward along the second through hole 9 under the action of its own gravity until the lower end of the second rail 13 abuts against the platform plate 3.

[0054] During the downward movement of the shelf 27, when the shelf 27 is lowered to a certain height, the push rod 22 has been separated from the mounting rod 7 at this time. The rack 30 will gradually approach the gear 17 and engage with the gear 17, the rack 30 drives the gear 17 to rotate counterclockwise, the gear 17 drives the shaft rod 15 to rotate counterclockwise through the second one-way bearing 18, the shaft rod 15 drives the mounting rod 7 to rotate counterclockwise, the mounting rod 7 drives the first rail 11 and the second rail 13 to rotate counterclockwise, and the first rail 11 drives the materials to rotate counterclockwise. When the gear 17 is disengaged from the rack 30, the mounting rod 7 has just rotated counterclockwise by 90 degrees. Then the second rail 13 is in a horizontal state and is in the storage slot 19, and the first rail 11 is in a vertical upward state and blocks the gap of the fence 5. During the counterclockwise rotation of the first rail 11, due to the fact that the friction coefficients at both ends of the first sliding groove 12 and the second sliding groove 14 are smaller than the friction coefficient in the middle, the first rail 11 can move downward along the first through hole 8 under the action of its own gravity, and the second rail 13 cannot slide downward along the second through hole 9 under the action of its own gravity. When the first rail 11 is vertically upward, the lower end of the first rail 11 abuts against the corresponding second rail 13. The materials fall on the platform plate 3. Then the materials can be moved from the platform plate 3 to the construction point.

[0055] When the shelf 27 rises again, the shelf 27 drives the second rail 13 to extend outward from the storage slot 19 through the first transmission assembly.
