Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a lifting trolley for installing a steel mesh. Background Art

[0002] The steel mesh for bridge deck leveling layer is usually made of customized steel welded mesh, which is produced by professional manufacturers and transported to the site for installation and forming. Due to the length and width restrictions of transportation vehicles, the steel welded mesh is generally about 2.5m wide and 6.0m long.

[0003] The diameter of the steel bar of the welded steel mesh varies with the thickness of the bridge deck leveling layer. Generally, for a 6cm thick leveling layer, the diameter of the mesh bar is 6mm, for an 8cm thick leveling layer, the diameter of the mesh bar is 8mm, and for a 12cm thick leveling layer, the diameter of the mesh bar is 12mm. As the thickness of the bridge deck leveling layer increases, the weight of a single mesh also increases, especially when the diameter of the mesh bar reaches 12mm, the weight of a single mesh can reach 220kg to 250kg.

[0004] For mesh with steel bar diameter of 8mm or less, it is usually lifted by 3 to 4 people and then installed in place. However, if the diameter of the mesh steel bar exceeds 8mm, it is generally carried and installed by 6 to 8 people, or lifted by a crane.

[0005] However, the former installation method consumes more manpower and has high labor intensity for workers. If workers fail to hold the device firmly and drop it, it is easy to cause personal injury.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, a lifting trolley for installing a steel mesh comprises a support frame 1, walking wheels 2, a control lever 3 and a binding mechanism 4.

[0021] like Figure 1 As shown, the support frame 1 includes a horizontal frame 11 and a pair of vertical frames 12. The horizontal frame 11 is horizontally arranged, and the pair of vertical frames 12 are distributed at both ends of the horizontal frame 11. The walking wheel 2 is rotatably arranged at the lower end of each vertical frame 12, so that the whole trolley can conveniently walk on the ground.

[0022] like Figure 1 As shown, the crossbar of the control lever 3 is arranged in the middle of the horizontal frame 11, and handrails 31 are arranged at both ends. A plurality of reinforcing rods 13 fixed to the control lever 3 are arranged on the horizontal frame 11 and the vertical frame 12 to increase the stability and structural strength of the control lever 3 and the entire support frame 1.

[0023] like Figure 1 As shown, the binding mechanism 4 is arranged on the control rod 3 and distributed on the front and rear sides of the horizontal frame 11, and is used to bind and fix the steel mesh plate. Binding belts 5 are arranged at both ends of the control rod 3, which can further increase the stability of the steel mesh during lifting and ensure safe construction.

[0024] When the steel mesh needs to be hoisted, the trolley is controlled to move on the ground, so that the trolley moves to the top of the steel mesh to be hoisted, and the binding mechanism 4 is located above the two ends of the steel mesh. Then one of the handrails 31 is controlled to move downward, so that the entire handrail 31 is turned downward, and then the binding mechanism 4 on this side is used to connect and fix the ends of the steel mesh, and the binding belt 5 can also be tied and fixed at the same time, so as to achieve double fixation of the steel mesh.

[0025] Then the other handrail 31 is controlled to move downward, and under the action of the lever principle, one end of the steel mesh that has been tied is tilted up more labor-savingly, and the steel mesh is also tilted up. Then the other end of the steel mesh is tied and fixed by the binding mechanism 4 at the other end, and the binding belt 5 is tied and fixed at the same time, so that the two ends of the steel mesh are double fixed.

[0026] Finally, the handrail 31 is controlled to move upward again to make the control rod 3 in a horizontal state. At the same time, the steel mesh is hoisted and fixed on the trolley by utilizing the cooperation of the binding mechanism 4 and the binding belt 5, and then the trolley is pushed to move, so that the lifting operation of the steel mesh can be realized.

[0027] Therefore, by setting up a trolley with an ingenious structure and easy operation, the two ends of the steel mesh can be quickly fixed at the construction site, and the steel mesh can be quickly transported to the installation position by utilizing the movement of the trolley. Only a small amount of manpower is needed to complete the operation, thereby minimizing the human resource consumption in the mesh installation process and reducing the labor intensity of workers. At the same time, no crane or hoist is required, and the construction cost is not increased during construction.

[0028] like Figure 1 , Figure 2 As shown, the binding mechanism 4 includes a mounting tube 41, a pair of sliding rods 42, a spring 43 and a driving member 6. The mounting tube 41 is tilted on the operating rod 3 and is used to be perpendicular to the ground after the operating rod 3 is flipped. A pair of sliding rods 42 are horizontally slidably connected to the lower end side walls on both sides of the mounting tube 41 and are used to hook a pair of adjacent steel bars on the upper layer of the steel mesh. The upper end surface of the sliding rod 42 is provided with a positioning groove 44 for the upper layer of steel bars to be embedded, so as to increase the stability between the sliding rod 42 and the steel bars. The spring 43 is provided at the inner end of the sliding rod 42 and is used to control the sliding rod 42 to slide inward.

[0029] like Figure 1 , Figure 2 As shown, the driving member 6 is used to control the sliding rod 42 to slide outward, and the driving member 6 includes a driving rod 61 , a driving block 62 , a tension spring 63 and a locking member 7 .

[0030] like Figure 1 , Figure 2 As shown, the driving rod 61 is vertically slidably connected to the lower end surface of the mounting tube 41, and the driving block 62 is arranged at the upper end of the driving rod 61. The driving block 62 is arranged in a wedge shape, and the end of the sliding rod 42 is arranged in an inclined surface and fits with the side wall of the driving block 62. The tension spring 63 is arranged on the driving rod 61 and is used to control the driving rod 61 to slide downward.

[0031] like Figure 1 , Figure 2 As shown, the locking member 7 is used to fix the driving block 62 , and the locking member 7 includes a locking rod 71 , a locking plate 72 and a locking column 73 .

[0032] like Figure 1 , Figure 2 As shown, the lower end of the locking rod 71 is rotatably connected to the upper end of the driving block 62, the locking plate 72 is arranged in the mounting tube 41, the locking column 73 is arranged at the upper end of the locking rod 71, and the locking plate 72 is provided with a locking groove 74 for the locking column 73 to slide.

[0033] like Figure 1 , Figure 2As shown, the locking groove 74 includes a forward groove 75, a retracting groove 76 and a connecting groove 77. The lower ends of the forward groove 75 and the retracting groove 76 are connected to each other, and the upper ends gradually move away from each other. The inner side of the connecting position of the lower ends of the forward groove 75 and the retracting groove 76 is inclined toward the retracting groove 76, and the connecting groove 77 is arranged in an M shape, and the outer side is inclined toward the forward groove 75.

[0034] When the control lever 3 is flipped downward and the steel mesh is tied and fixed, the lower end of the mounting tube 41 is gradually inserted into the rectangular hole of the steel mesh. When the driving rod 61 at the lower end of the mounting tube 41 touches the ground, as the control lever 3 continues to apply pressure, the driving rod 61 slides upward. At this time, the driving rod 61 drives the driving block 62 to move synchronously, and under the cooperation of the driving block 62 and the inclined surface on the sliding rod 42, the sliding rod 42 slides outward and extends to the bottom of the two adjacent upper steel bars of the steel mesh.

[0035] When the driving block 62 slides, the driving block 62 drives the locking rod 71 to move synchronously, and the locking rod 71 drives the locking column 73 to slide upward along the lower position of the forward groove 75, and after being guided by the connecting groove 77, it automatically fits into the middle corner position of the connecting groove 77. At the same time, under the pulling force of the tension spring 63 on the driving rod 61, the locking column 73 is indirectly fixed in the connecting groove 77, thereby fixing the position of the sliding rod 42.

[0036] Then, as the control lever 3 flips upward, the mounting tube 41 and the sliding rod 42 can be driven to move synchronously. At this time, the sliding rod 42 supports and clamps the steel mesh, thereby enabling automatic bundling of the steel mesh and subsequent efficient lifting operations.

[0037] When the steel mesh needs to be placed at the construction location, the control lever 3 is controlled to flip downward again, and the control lever 3 drives the installation tube 41 to move downward. When the driving rod 61 at the lower end of the installation tube 41 touches the ground, the driving rod 61 slides upward as the control lever 3 continues to apply pressure, and the driving rod 61 drives the driving block 62 to move synchronously, and the driving block 62 cooperates with the inclined surface on the sliding rod 42 to make the sliding rod 42 continue to slide outward.

[0038] When the driving block 62 slides, the driving block 62 drives the locking rod 71 to move synchronously, and the locking rod 71 drives the locking column 73 to gradually slide along the connecting groove 77 into the retreat groove 76, and finally resets to the lower end position of the forward groove 75. At the same time, under the pulling force of the tension spring 63 on the driving rod 61, the driving rod 61 drives the driving block 62 to slide downward, so that the driving block 62 is separated from the end position of the sliding rod 42. At this time, under the pulling force of the spring 43, the sliding rod 42 retreats into the installation tube 41, releasing the support for the steel mesh. At this time, the steel mesh automatically falls off, realizing the automatic unloading operation of the steel mesh.

[0039] Therefore, by setting up a highly automated bundling mechanism 4, the two ends of the steel mesh can be quickly hooked and fixed during the tilting process of the trolley, making the lifting process of the steel mesh more efficient and convenient, which can save labor and improve construction efficiency.

[0040] like Figure 2 As shown, the mounting tube 41 includes an upper tube 45 and a lower tube 46. The upper tube 45 is connected to the control rod 3, and the lower tube 46 is arranged below the upper tube 45. A plug 47 for plugging the upper tube 45 is vertically arranged on the lower tube 46 to increase the stability of the connection position. A hook 48 is vertically arranged upward on the lower tube 46, and a clamping ring 49 for the hook 48 to pass through is arranged on the upper tube 45.

[0041] Therefore, by setting the mounting tube 41 in sections and setting all the components of the binding mechanism 4 in the lower tube 46, the binding mechanism 4 can be freely switched between the use state and the non-use state. When the binding mechanism 4 is not in use, the upper tube 45 can form a support leg, which is convenient for the entire trolley to be placed on the ground. At the same time, when the components of the binding mechanism 4 are damaged, the lower tube 46 can be disassembled and then repaired or replaced. Quick replacement can also ensure that the trolley can work again in time to avoid affecting the construction progress.

[0042] like Figure 1 , Figure 3 As shown, the handrail 31 includes an inner tube 32, an outer tube 33 and a cross bar 34. The inner tube 32 is fixed to the end of the control rod 3, the outer tube 33 is slidably connected to the outer wall of the inner tube 32, and the cross bar 34 is transversely arranged at the end of the outer tube 33. The outer tube 33 is horizontally threaded with a locking pin 35, and the inner tube 32 is provided with a row of locking holes 36 for the locking pin 35 to pass through.

[0043] Therefore, in actual use, the expansion and contraction of the inner tube 32 and the outer tube 33 can be adjusted according to the weight of the steel mesh to be lifted, so as to adjust the length of the entire handrail 31 and increase the length of the lever arm, which saves more effort when lifting the steel mesh using the lever principle and improves construction convenience.

[0044] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
