Description

Technical Field

[0001] The utility model belongs to the technical field of lifting devices, and in particular relates to a manned lifting device for construction. Background Art

[0002] Manned lifting devices are often used in construction. The devices are mainly used to vertically transport construction workers to a predetermined height for construction. In order to improve the passability, the existing manned lifting devices usually have a narrower base, which leads to poor anti-overturning ability of the manned lifting devices.

[0003] A Chinese patent with publication number CN219429652U discloses a lifting frame with a protective structure, which includes a base plate, a lifting frame body is fixedly installed on the top surface of the base plate, and slot groups are symmetrically provided on opposite sides of the base plate, and the slot groups include two slots arranged on one side of the base plate and close to both ends and parallel to each other, an extension plate is slidably inserted in the slot, and a vertically arranged screw hole is provided at the end of the extension plate, and a screw rod is threadedly connected in the screw hole, and the bottom of the screw rod extends from the bottom surface of the extension plate, and a support plate is fixed thereon. The above scheme utilizes rotating the screw rod to change the length of the screw rod extending out of the extension plate, and at the same time pushes the support plate to move so that the support plate contacts the ground, thereby supporting and protecting the lifting frame body and adjusting its horizontal state at the same time.

[0004] When the above solution is used, in order to move the screw rods at the ends of the extension plates to the predetermined positions, each extension plate needs to be pulled and fixed one by one. This operation step is relatively cumbersome, resulting in low installation efficiency of the above solution. Utility Model Content

[0005] The utility model aims to provide a manned lifting device for construction to solve the problem of low installation efficiency in the above-mentioned solution.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A manned lifting device for construction construction comprises a base plate and a rotating shaft, a lifting machine body is fixedly arranged on the top of the base plate, a walking mechanism is fixedly arranged on the bottom of the base plate, slot groups are respectively arranged on the left and right sides of the base plate, the slot groups comprise two grooves symmetrically arranged on the side wall of the base plate, support mechanisms are arranged in the grooves, the support mechanism comprises a cross bar, a first screw rod and a moving rod, one end of the cross bar is slidably inserted in the groove, a slide groove is recessed at the bottom of the other end of the cross bar, the first screw rod is rotatably inserted into the top of the slide groove, the top of the moving rod is slidably embedded in the slide groove and is cooperatively sleeved on the bottom of the first screw rod, a support plate is arranged at the bottom of the moving rod, the rotating shaft is rotatably inserted in the base plate, and each cross bar is transmission-connected to the rotating shaft through a transmission assembly.

[0008] The principle and effect of this technical solution:

[0009] When in use, the device is transferred to the construction position, the rotating shaft is rotated, and the cross bars are driven to move to the predetermined positions away from the base plate. According to the actual terrain, the first screw rods are rotated, and the moving rods move downward with the rotation of the first screw rods until the walking mechanism leaves the ground and the base plate is adjusted to a horizontal level. The lift body can then be started to lift the construction personnel to the specified height for construction.

[0010] Through the above arrangement, by rotating the shaft, multiple sets of transmission components are used to simultaneously drive multiple cross bars to move away from the base plate, which makes it convenient for workers to fix the device at the location to be constructed, simplifies the operation steps, and improves work efficiency.

[0011] In the utility model, the transmission assembly includes a first bevel gear, a second bevel gear and a second screw. The first bevel gear is fixedly sleeved on the rotating shaft, and the second screw is rotatably inserted in the groove. A screw hole is recessed at one end of the cross bar, and one end of the second screw is cooperatively inserted in the screw hole. The second bevel gear is fixedly sleeved on the other end of the second screw, and the first bevel gear is meshed with the second bevel gear.

[0012] The principle and effect of this technical solution:

[0013] The rotation of the rotating shaft drives the first bevel gear to rotate. Since the first bevel gear meshes with the second bevel gear, the second bevel gear and the second screw are driven to rotate. Since the groove restricts the rotation of the crossbar, the crossbar moves laterally as the second screw rotates.

[0014] Through the above arrangement, the purpose of rotating the rotating shaft and driving each cross bar to move to a predetermined position in a direction away from the bottom plate is achieved.

[0015] In the utility model, the side wall of the slide groove is vertically provided with a convex strip, the side wall of the moving rod is vertically provided with a limiting groove, and the convex strip is slidably embedded in the limiting groove. Through the above arrangement, the convex strip limits the rotation of the moving rod, so that the moving rod moves vertically along with the rotation of the first screw rod.

[0016] In the utility model, a ball pin is fixedly arranged at the bottom of the moving rod, a ball seat is fixedly arranged at the top of the support plate, and the ball seat is sleeved on the ball pin. Through the above arrangement, when the ground is tilted, the bottom of the support plate can be closely attached to the ground, and the bottom plate can be adjusted to be in a horizontal state.

[0017] In the utility model, one end of the screw hole penetrates through the inner wall of the slide slot, and a notch is recessed on the side wall of the moving rod. One end of the second screw rod can extend into the slide slot and be inserted into the notch.

[0018] The principle and effect of this technical solution:

[0019] In the initial state, the moving rod moves to a high position and the cross rod extends into the groove. At this time, the second screw protrudes from the inner wall of the slide groove and is inserted into the notch. When in use, the cross rod must be moved outward first to expand the supporting area. At this time, the moving rod is away from the second screw, and the second screw is disengaged from the notch. The moving rod can move downward as the first screw rotates. If the first screw is rotated without moving the cross rod, the top of the second screw will abut against the top of the notch to prevent the moving rod from moving downward.

[0020] Through the above-mentioned arrangement, it is possible to prevent construction workers from lowering the moving rod without moving the cross bar outward, standardize the operating process, ensure support and protection for the elevator body, and improve the safety of the utility model.

[0021] In the present invention, the walking mechanism comprises a plurality of walking wheels fixed to the bottom of the base plate and provided with a locking mechanism. Through the above arrangement, the construction workers can conveniently move the present invention.

[0022] In the utility model, a rotating handle is fixedly arranged on the top of the first screw rod. Through the above arrangement, it is convenient for construction workers to rotate the first screw rod, thereby improving the practicality of the utility model.

[0023] In the utility model, a motor is fixedly arranged on the right side wall of the bottom plate, and the output shaft of the motor is drivingly connected to the rotating shaft. Through the above arrangement, it is convenient for construction workers to rotate the rotating shaft, further improving the practicality of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, the transmission assembly includes a first bevel gear 51, a second bevel gear 52 and a second screw 53. The first bevel gear 51 is fixedly sleeved on the rotating shaft 40, and the second screw 53 is rotatably inserted in the groove 11. A screw hole 313 is recessed at one end of the cross bar 31, and one end of the second screw 53 is cooperatively inserted in the screw hole 313. The second bevel gear 52 is fixedly sleeved on the other end of the second screw 53, and the first bevel gear 51 is meshed with the second bevel gear 52.

[0034] In this embodiment, a convex strip 312 is vertically arranged on the side wall of the sliding groove 311 , and a limiting groove 331 is vertically formed on the side wall of the moving rod 33 , and the convex strip 312 is slidably embedded in the limiting groove 331 .

[0035] In this embodiment, a ball pin 332 is fixedly provided at the bottom of the moving rod 33 , and a ball seat 341 is fixedly provided at the top of the supporting plate 34 . The ball seat 341 is sleeved on the ball pin 332 .

[0036] In this embodiment, one end of the screw hole 313 passes through the inner wall of the slide slot 311 , and a notch 333 is recessed on the side wall of the moving rod 33 . One end of the second screw rod 53 can extend into the slide slot 311 and be inserted into the notch 333 .

[0037] In this embodiment, the walking mechanism includes a plurality of walking wheels 60 fixed to the bottom of the base plate 10 and provided with a locking mechanism.

[0038] In this embodiment, a rotating handle 321 is fixedly disposed on the top of the first screw rod 32 .

[0039] In this embodiment, a motor 70 is fixedly disposed on the right side wall of the bottom plate, and an output shaft of the motor 70 is transmission-connected to the rotating shaft 40 .

[0040] The specific implementation process is as follows:

[0041] When in use, the device is transferred to the construction site, the rotating shaft 40 is rotated, and the cross bars 31 are driven to move to the predetermined positions in the direction away from the base plate 10 respectively. According to the actual terrain, the first screw rods 32 are rotated, and the moving rods 33 move downward with the rotation of the first screw rods 32 until the walking mechanism leaves the ground and the base plate 10 is adjusted to a horizontal level. Then the lift body 20 can be started to lift the construction personnel to the specified height position for construction.

[0042] The rotation of the rotating shaft 40 drives the first bevel gear 51 to rotate. Since the first bevel gear 51 is meshed with the second bevel gear 52, the second bevel gear 52 and the second screw 53 are driven to rotate. Since the groove 11 restricts the rotation of the cross bar 31, the cross bar 31 moves laterally with the rotation of the second screw 53.

[0043] In the initial state, the moving rod 33 moves to a high position and the cross bar 31 extends into the groove 11. At this time, the second screw 53 protrudes from the inner wall of the slide groove 311 and is inserted into the notch 333. When in use, the cross bar 31 must be moved outward first to expand the supporting area. At this time, the moving rod 33 is away from the second screw 53, and the second screw 53 is disengaged from the notch 333. The moving rod 33 can move downward as the first screw 32 rotates. If the first screw 32 is rotated without moving the cross bar 31, the top of the second screw 53 will abut against the top of the notch 333, preventing the moving rod 33 from moving downward.

[0044] When the device needs to be stored after use, the moving rod 33 is first moved to a high position so that the notch 333 is at the same height as the second screw rod 53, and then the cross bar 31 is moved back into the groove 11. The structure can be designed so that when the moving rod 33 is moved up to make the ball seat 341 abut against the bottom of the cross bar 31, the notch 333 is at the same height as the second screw rod 53. In this state, the width of the device is the smallest, which is convenient for loading and transportation.
