Description

Technical Field

[0001] This utility model belongs to the field of vibration reduction and isolation equipment installation and construction technology, specifically relating to a damper transportation device in a confined space. Background Technology

[0002] Large seismic isolation devices, such as dampers and seismic isolation bearings, are heavy, long, and have a high center of gravity. They are often installed in construction spaces such as structural mezzanines, floor transfer zones, and vertical shafts. Their transportation and installation present significant technical bottlenecks. Currently, forklifts and cranes combined with rollers and I-beam rails are commonly used to move dampers within confined spaces. This method is not only inefficient but also requires highly skilled operators and is prone to causing damage to the structure or the device itself, posing significant construction safety hazards.

[0003] Existing similar transportation and installation equipment lacks the ability to turn small radius and has high stability sliding function, and cannot realize the integrated function of directional positioning and in-situ deployment, which greatly increases the construction period and cost in confined spaces. Summary of the Invention

[0004] The purpose of this invention is to provide a damper transport device for confined spaces, in order to solve the problem that the existing technology cannot achieve the integrated function of directional positioning and in-situ placement, which greatly increases the construction period and cost in confined spaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A confined space damper transport device, characterized in that it includes a placement platform and a hoisting mechanism fixed to the placement platform;

[0007] The placement platform is a movable flat platform; push rods for pushing and control are fixedly connected to both ends of the placement platform, and walking devices are set at the four corners of the lower surface;

[0008] The lifting mechanism is a hydraulic cylinder driven vehicle-mounted lifting mechanism, consisting of a hydraulic cylinder, a boom, and a lifting plate; the hydraulic cylinder is fixed to one side of the placement platform; the output shaft of the hydraulic cylinder is driven and fixed to the horizontally set boom; a circular lifting plate is connected to the lower part of the other end of the boom; two sets of lifting devices for connecting and fixing dampers are symmetrically arranged on the lifting plate.

[0009] The lifting device further includes: a movable groove arranged radially along the edge of the lifting plate, a movable lifting block suspended in the movable groove, and a lifting chain and a hook suspended below the movable lifting block; the outer end of the movable groove is closed by a baffle fixed to the side of the lifting plate.

[0010] Furthermore, the moving groove is a T-shaped groove structure, and the moving block has a T-shaped cross-sectional structure that matches the T-shaped groove of the moving groove and is slidably suspended in the T-shaped groove of the moving groove.

[0011] Furthermore, the walking device is a caster wheel device, which is provided with a lockable horizontally rotating socket and a plug rod.

[0012] The walking device further includes: a support block fixedly connected to the bottom surface of the placement platform 1; a turntable with a circular trapezoidal structure connected below the support block; the circular trapezoidal structure of the turntable is rotatably connected to a circular trapezoidal groove matched in the movable frame; and a moving wheel is provided below the movable frame. The insertion hole is radially arranged on the side of the movable frame and the turntable is stopped by the insertion rod.

[0013] Furthermore, the placement platform is equipped with at least four sets of fixing mechanisms at the four corners of the plane where the damper is placed for limiting and fixing the damper; each set of fixing mechanisms includes: a connecting groove arranged radially on the surface of the placement platform, a vertically arranged control plate fixed at the outer end of the connecting groove, a control rod of the screw structure passing through the control plate, and a wedge-shaped abutment slidably arranged in the connecting groove, the back of the abutment being driven and connected to the control rod in the connecting groove for limiting movement.

[0014] Furthermore, a T-shaped limiting groove is provided at the bottom of the connecting groove, and a protrusion is provided below the abutment to limit the sliding within the limiting groove to prevent the abutment from slipping off.

[0015] Furthermore, the output shaft of the hydraulic cylinder is fixedly connected to the horizontally positioned boom via a reinforcing plate; a connecting shaft is provided on the upper surface of the circular lifting plate, and the connecting shaft is fixedly connected to the lower end of the boom.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model device is equipped with a hoisting mechanism on the placement platform. Under the operation of the hydraulic cylinder and boom of the hoisting mechanism, the damper is hoisted and its position adjusted on the placement platform through the connection of the hoisting plate and the hoisting chain. This facilitates the transportation and placement of the damper. Furthermore, the sliding connection of the moving groove and the moving block changes the position of the hoisting chain on the hoisting plate, improving its hoisting range and performance. Under the action of the traveling device, the overall transportation and movement are realized.

[0018] This utility model's walking device achieves a rotatable connection between a support block and a turntable through the interlocking rotation of the turntable and the rotating groove, thus realizing the rotatable connection between the support block and the movable frame. The rotation angle between the support block and the movable frame can be controlled via a through-hole and rod connection. When no position-limiting operation is performed, the rotation of the two sets of moving wheels on the placement platform allows the wheels to move and turn the platform. When a position-limiting operation is performed, all four sets of moving wheels can rotate on the placement platform, reducing the turning radius and facilitating movement in confined spaces. This allows the damper to be transported to a specific location, thereby facilitating the placement and limitation of the damper's position.

[0019] This utility model sets up multiple fixing mechanisms on the placement platform. The fixing mechanism includes an adjustment rod and an adjustment plate. The adjustment rod adjusts the sliding of the abutment in the connecting groove, changing the fixed position of the abutment on the placement platform, so that the abutment is in adaptive contact with the outer surface of the damper, thereby achieving the support and limiting of the damper on the placement platform.

Through the connection between the placement platform 1 and the push rods 11, the damper 3 can be transported under the action of the push rods 11 and the walking devices 4. The placement platform 1 can also be equipped with a motor and battery for driving.

[0031] The hoisting mechanism 2 consists of a hydraulic cylinder 20, a boom 21, a lifting plate 22, and lifting devices 29, and is mounted on the placement platform 1. The output shaft of the hydraulic cylinder 20 is connected to the boom 21, and the lifting plate 22 is movably connected to the surface of the boom 21. Two sets of lifting devices 29 are symmetrically arranged on the lifting plate 22. The damper 3 is hoisted and placed on the placement platform 1, below the lifting plate 22.

[0032] The lifting device 29 in this embodiment includes: a radially symmetrically arranged moving groove 23 on the surface of the lifting plate 22; a moving block 25 slidably connected to the inner side of the moving groove 23; a lifting chain 24 fixedly connected to the lower surface of the moving block 25; a screw hole 26 is opened on the outer circumferential surface of the moving groove 23; a screw rod 28 is threadedly connected to the inner side of the screw hole 26; and a baffle 27 is connected to the outer side of the moving groove 23 through the screw rod 28 and the screw hole 26 to close the outer end of the moving groove 23.

[0033] In this embodiment, the hanging plate 22 is disc-shaped. The hanging chain 24 is slidably connected to the hanging plate 22 through the moving block 25 and the moving groove 23. The end of the hanging chain 24 away from the moving block 25 is movably connected to a hook. Through the connection of the hydraulic cylinder 20 and the boom 21, the damper 3 can be hoisted, placed and moved on the placement platform 1 under the connection of the hanging plate 22 and the boom 21. The hydraulic cylinder 2 is controlled by the relevant drive control equipment to realize the lifting and hoisting.

[0034] In this embodiment, a movable groove 23 is radially provided on the hanging plate 22, and the movable block 25 moves in the movable groove 23. With the connection between the hanging chain 24 and the movable block 25, the position of the hanging chain 24 on the hanging plate 22 can be adjusted. The baffle 27 and the screw 28 are connected and fixed by the screw hole 26, which limits the movable block 25 in the movable groove 23 to prevent it from slipping out.

[0035] The walking device 4 in this embodiment includes: a support block 41 fixedly connected to the bottom surface of the placement platform 1; the support block 41 is connected to a turntable 42; a through hole is provided through the surface of the turntable 42; the support block 41 is movably connected to a movable frame 43 through the turntable 42; a rotating groove 44 is provided in the middle of the movable frame 43; an insertion hole 45 is provided radially through the movable frame 43; an insertion rod 46 is connected through the insertion hole 45; the other end of the insertion rod 46 is threaded with a threaded sleeve 47; and a moving wheel 40 is provided below the movable frame 43 to achieve walking.

[0036] In this embodiment, the turntable 42 is a circular trapezoidal structure with two steps. The movable frame 43 is provided with a circular stepped structure cavity groove 44 that matches the circular trapezoidal structure of the two steps of the turntable 42. The turntable 42 can be rotatably installed in the movable frame 43 through the groove 44. The moving wheel 40 is rotatably connected to the placement platform 1 through the movable frame 43 and the support block 41. Through the connection between the support block 41 and the turntable 42, the rotational connection effect between the movable frame 43 and the support block 41 is achieved with the cooperation of the turntable 42 and the groove 44.

[0037] The insertion rod 46 passes through the through hole opened on the surface of the turntable 42 through the insertion hole 45. The walking device 4 is distributed in four groups at the four corners of the lower surface of the placement platform 1. Through the connection between the insertion hole 45 and the movable frame 43, and with the through connection between the insertion rod 46 and the insertion hole 45, the insertion rod 46 and the through hole on the turntable 42 are connected, thereby achieving the effect of controlling the rotation angle of the turntable 42 in the rotating groove 44.

[0038] Four sets of fixing mechanisms 5 are provided on the upper surface of the placement platform 1. The fixing mechanism 5 includes a connecting groove 50 with a groove structure on the surface of the placement platform 1. An adjustment plate 51 is fixedly provided at the outer end of the connecting groove 50. An adjustment rod 52 is connected through the surface of the adjustment plate 51. The inner end of the adjustment rod 52 is movably connected to a stop block 53. The stop block 53 has a wedge-shaped structure and its inner side is set with an arc-shaped inclined surface that matches the outer surface of the damper 3. The stop block 53 and the outer surface of the damper 3 are in contact. A limiting groove is provided at the bottom end of the connecting groove 50. The slider protrusion below the stop block 53 is limited to slide in the limiting groove to prevent the stop block 53 from slipping off. The adjustment rod 52 is rotatably connected to the stop block 53 by thread through the surface of the adjustment plate 51. Through the threaded connection between the adjustment plate 51 and the adjustment rod 52, the position of the stop block 53 in the connecting groove 50 is changed by the rotation of the adjustment rod 52, so as to achieve the supporting and limiting effect of the damper 3 on the placement platform 1.

[0039] Working principle: When transporting the damper 3 in a confined space, the hydraulic cylinder 20 and the lifting plate 22 of the hoisting mechanism 2 are used, and the lifting device 29 is used to complete the hoisting operation of the damper 3. The walking device 4 moves the placement platform 1 to complete the transport operation of the damper 3. After reaching the corresponding position, especially when moving in a confined space, the insertion rod 46 can be pulled out to allow the movable frame 43 and the support block 41 to rotate. The placement platform 1 can reduce the turning radius, which is convenient for operation. Under the action of the abutment block 53, the position of the damper 3 on the placement platform 1 can be limited and supported, which improves the stability of its transport.
