Description

Technical Field

[0001] The utility model belongs to the technical field of electric lifting platforms, and particularly relates to an attached electric lifting platform with a narrow platform. Background Technique

[0002] An attached electric lifting platform is a device specifically used for building and high-rise construction. It is attached to the facade or structure of a building and uses an electric motor to drive the lifting of the platform, thereby realizing the vertical transportation of workers and materials. Compared with traditional scaffolding or tower cranes, the attached electric lifting platform has the advantages of high flexibility, strong safety, and simple operation.

[0003] After retrieval, in the prior art, the Chinese patent publication number: CN209113410U, authorization date: July 16, 2019, discloses a lifting platform, which belongs to the technical field of material lifting devices. It includes a tabletop and a bottom frame. A folding arm is rotatably connected between one side of the bottom of the tabletop and one side of the top of the bottom frame. The top end of the bottom frame is fixedly connected with a first hydraulic telescopic cylinder, and the telescopic end of the first hydraulic telescopic cylinder is fixedly connected to the center of the folding arm. The two ends of the top of the tabletop are respectively rotatably connected with baffles, and a protective net is fixedly connected between the two baffles. The two ends of the side wall of the tabletop are respectively fixedly connected with second hydraulic telescopic cylinders. It mainly uses the closing of the two baffles, the protective net, and two U-shaped blocks, as well as the triple protection of the manned platform, so that when the construction personnel are lifted by the tabletop, they will not be injured due to the rise of the tabletop, thus solving the problem that when the lifting platform is in lifting operation, there is a lack of personal safety protection devices on the lifting platform, which poses a great threat to the personal safety of construction personnel.

[0004] However, this device still has the following defects: Although the staff can be protected by the baffles, the protective net and the U-shaped blocks, reducing the risk of the staff falling from the platform and increasing the safety of the staff during construction, when the first hydraulic cylinder operates to drive the manned platform to move up and down, regardless of the number of staff and objects, the weight of the manned platform remains unchanged. This makes the first hydraulic cylinder need to carry the weight of the manned platform itself to move up and down each time it operates, which not only increases the load on the first hydraulic cylinder, but also easily increases the instability during use and the consumption of materials due to the heavy weight. Moreover, when the manned platform needs to be expanded, the expansion operation is relatively cumbersome and inconvenient. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides an attached electric lifting platform with a narrow platform, which includes an electric lifter body and a connecting plate. The connecting plate is arranged on the upper side of the electric lifter body. A manned platform and a connecting mechanism are arranged on the upper side of the connecting plate, and the connecting mechanism is arranged outside the manned platform;

[0006] The manned platform includes a bottom plate disposed on the upper side of the connecting plate. The outer side of the bottom plate is fixedly connected with a triangular truss.

The upper side of the connecting steel plate is fixedly connected with a fixing steel plate, and there are multiple fixing steel plates. The upper sides of the multiple fixing steel plates are fixedly connected with a walkway plate, and an armrest is arranged on the upper side of the walkway plate.

[0007] Furthermore, the connecting mechanism includes a first fixing plate and a fixing block fixedly connected to the upper side of the connecting plate. The upper side of the fixing block is fixedly connected with a cylinder. The output end of the cylinder is drivingly connected with a moving plate. First threaded holes are formed in one sides of the bottom plate, the first fixing plate and the moving plate, and first bolts are arranged inside the first threaded holes.

[0008] Furthermore, reinforcing blocks are fixedly connected between the multiple fixing steel plates, and the reinforcing blocks are fixedly connected between the connecting steel plate and the walkway plate.

[0009] Furthermore, reinforcing inclined plates are fixedly connected to one sides of the multiple reinforcing blocks, and second fixing plates are fixedly connected between the multiple fixing steel plates.

[0010] Furthermore, a reinforcing rod is fixedly connected to one side of the bottom plate, and the upper end of the reinforcing rod is fixedly connected with the connecting steel plate. First mounting plates and second mounting plates are fixedly connected to one sides of the fixing steel plates located on both sides. A second threaded groove is formed in the upper side of the first mounting plate, and a third threaded groove is formed in the upper side of the second mounting plate.

[0011] Furthermore, a connecting block is fixedly connected to one side of the armrest. Fourth threaded grooves are formed in the upper sides of the walkway plate and the connecting block, and second bolts are arranged inside the fourth threaded grooves.

[0014] The beneficial effects of the utility model are:

[0015] 1. In this device, due to the narrow width of the electric lifter body, the load borne by the electric lifter body during operation can be effectively reduced. When it is not necessary to move a large number of workers or materials, it is not easy to be damaged or become unstable due to a large bearing weight. At the same time, through the operation of the cylinder and the movement of the moving plate, the expansion of the walkway plate can be achieved. And because the walkway plate has expandability, the size of the walkway plate itself does not need to be large, thus further reducing material loss.

[0016] 2. In this device, the cylinder can operate to push the moving plate, so that the moving plate can cooperate with the first fixing plate to clamp the bottom plate.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The embodiment of the present utility model provides an attached electric lifting platform narrow platform, including an electric lifter body 1 and a connecting plate 2. Exemplarily, as Figures 1 - 5 shown.

[0027] The connecting plate 2 is arranged on the upper side of the electric lifter body 1. A passenger platform 3 and a connecting mechanism 4 are arranged on the upper side of the connecting plate 2, and the connecting mechanism 4 is arranged outside the passenger platform 3.

[0028] The passenger platform 3 includes a bottom plate 31 arranged on the upper side of the connecting plate 2. A triangular truss 32 is fixedly connected to the outside of the bottom plate 31. The upper end of the triangular truss 32 is fixedly connected to a connecting steel plate 33. A fixed steel plate 34 is fixedly connected to the upper side of the connecting steel plate 33, and a plurality of the fixed steel plates 34 are provided. A walkway plate 35 is fixedly connected to the upper sides of the plurality of fixed steel plates 34, and a handrail 36 is arranged on the upper side of the walkway plate 35.

[0029] The connecting mechanism 4 includes a first fixing plate 41 and a fixed block 43 fixedly connected to the upper side of the connecting plate 2. A cylinder 44 is fixedly connected to the upper side of the fixed block 43. The output end of the cylinder 44 is drivingly connected to a moving plate 42. First threaded holes 45 are formed in one sides of the bottom plate 31, the first fixing plate 41 and the moving plate 42, and a first bolt 46 is arranged inside the first threaded holes 45.

[0030] Specifically, the electric lifter body 1 can drive the manned platform 3 to move up and down through the connecting plate 2. The manned platform 3 can be used to carry people, so as to raise the staff. The bottom plate 31 can connect the connecting steel plate 33 through the triangular truss 32, and connect the walkway plate 35 and the handrail 36 through the fixed steel plate 34. The handrail 36 can be used to protect the staff and reduce the situation of the staff falling;

[0031] In addition, the width of the walkway plate 35 is narrower than that of the existing platform. It can effectively reduce the load of the electric lifter body 1 during operation, and at the same time can be additionally extended through the connecting mechanism 4, which not only reduces the consumption of materials, but also greatly increases the stability of the manned platform 3 during use due to the small load;

[0032] In addition, the air cylinder 44 can operate to push the moving plate 42, so that the moving plate 42 can cooperate with the first fixing plate 41 to clamp the bottom plate 31. When the first bolt 46 is connected to the inside of the first threaded hole 45, the connection of the bottom plate 31, the first fixing plate 41 and the moving plate 42 can be realized, which can not only realize the use of the walkway plate 35, but also be convenient enough when additionally expanding the walkway plate 35.

[0033] Reinforcing blocks 5 are fixedly connected between multiple said fixed steel plates 34. The reinforcing blocks 5 are fixedly connected between the connecting steel plate 33 and the walkway plate 35, as Figures 2 - 5 shown.

[0034] Reinforcing inclined plates 62 are fixedly connected to one side of multiple said reinforcing blocks 5. Second fixing plates 61 are fixedly connected between multiple said fixed steel plates 34. One side of the reinforcing inclined plate 62 is fixedly connected to the second fixing plate 61.

[0035] One side of the bottom plate 31 is fixedly connected with a reinforcing rod 9. The upper end of the reinforcing rod 9 is fixedly connected with the connecting steel plate 33. First mounting plates 71 and second mounting plates 72 are fixedly connected to one side of the fixed steel plates 34 located on both sides. A second threaded groove 73 is opened on the upper side of the first mounting plate 71, and a third threaded groove 74 is opened on the upper side of the second mounting plate 72.

[0036] Specifically, the reinforcing block 5 can play an auxiliary and reinforcing role for the fixed steel plate 34, making the fixed steel plate 34 stable enough during use;

[0037] In addition, the second fixing plate 61 and the reinforcing inclined plate 62 can form multiple triangles, so as to increase the stability and firmness of the walkway plate 35, the fixed steel plate 34 and the connecting steel plate 33 during use through the stability of the triangle. The reinforcing rod 9 can play an auxiliary role in supporting the triangular truss 32. The settings of the second threaded groove 73 and the third threaded groove 74 can realize the expansion of the walkway plate 35.

[0038] One side of the handrail 36 is fixedly connected with a connecting block 81. Fourth threaded grooves 82 are provided on the upper sides of the walkway plate 35 and the connecting block 81. A second bolt 83 is arranged inside the fourth threaded groove 82, as Figures 2 - 5 shown.

[0039] A hollow groove 101 is provided on the upper side of the connecting plate 2. A runner 102 is arranged inside the hollow groove 101, and the runner 102 is rotatably connected to the inside of the connecting plate 2.

[0040] The vertical height of the first mounting plate 71 is higher than that of the second mounting plate 72. The diameters of the second threaded groove 73 and the third threaded groove 74 are the same.

[0041] Specifically, the settings of the fourth threaded groove 82 and the second bolt 83 enable the position of the handrail 36 to be moved by the staff after the walkway plate 35 is extended. While the handrail 36 plays a protective role, it is not easy to be inconvenient to move and affect the normal work of the staff.

[0042] In addition, the setting of the runner 102 enables the staff to move the extended walkway plate 35 more conveniently.

[0043] In addition, the vertical height of the first mounting plate 71 is higher than that of the second mounting plate 72. After the extended walkway plate 35 is connected to the upper side of the electric elevator body 1, the second mounting plate 72 originally installed on one side of the walkway plate 35 can be located below the first mounting plate 71 installed on one side of the extended walkway plate 35. Then, only by inserting devices such as screws into the inside of the second threaded groove 73 and the third threaded groove 74 and connecting the first mounting plate 71 and the second mounting plate 72 together, the further installation and fixation of the extended walkway plate 35 can be realized.

[0044] The working principle of an attached electric elevator narrow platform proposed by an embodiment of the present utility model is as follows: The device connects the first fixing plate 41, the moving plate 42 and the bottom plate 31 through the first bolt 46. Then, the walkway plate 35 is used to carry the staff, and the handrail 36 is used to protect the staff. Through the operation of the electric elevator body 1, the staff can also be driven to move up and down. At the same time, because the width of the electric elevator body 1 is relatively narrow, this can effectively reduce the load borne by the electric elevator body 1 during operation. When it is not necessary to move a large number of staff or materials, it is not easy to be damaged or unstable due to a large load, and at the same time, through the operation of the cylinder 44 and the movement of the moving plate 42, the expansion of the walkway plate 35 can be realized, so that the walkway plate 35 can adjust the bearing range according to the situation.

[0045] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
