Technical Field
[0001] This utility model relates to the field of handling device technology, and in particular to a handling device for rail transit water pumps. Background Technology
[0002] Rail transit water pumps are large and heavy, and are core equipment in the water supply, drainage, fire protection, and cooling systems. Currently, they are mainly handled manually, which is difficult, inefficient, labor-intensive, and dangerous.
[0003] To address the challenge of transporting water pumps for rail transit, several manufacturers have developed various water pump handling devices. For example, patent CN212195500U, titled "Motor Handling Device," includes a mobile platform vehicle, a hydraulic lifting mechanism, a support frame, and a counterweight. The fixed part of the hydraulic lifting mechanism is fixed to the front of the mobile platform vehicle, and its lifting part reciprocates along the height direction. The support frame is located below the fixed part of the hydraulic lifting mechanism and fixed to the front of the mobile platform vehicle. The counterweight is fixed to the mobile platform vehicle. In actual operation, the support frame is first inserted into the opposite sides of the water pump; then the hydraulic lifting mechanism lifts the water pump; finally, the pneumatic mobile platform vehicle moves the water pump to the predetermined position.
[0004] The aforementioned water pump handling device is flexible and efficient in its handling. However, rail transit water pumps are larger and heavier, making it easy for the mobile platform vehicle to tilt and cause the water pump to tip over during the lifting process. In addition, the hydraulic lifting mechanism needs to continuously output power to lift the water pump during the movement, which consumes a lot of energy.
[0005] Therefore, how to design a rail transit water pump handling device that is simple in structure, low in cost, stable in lifting, safe in handling, and low in energy consumption is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] This utility model provides a handling device for rail transit water pumps, which solves the technical problems of existing handling devices that easily tip over water pumps and consume a lot of energy.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a handling device for rail transit water pumps, comprising: a handling frame, a gantry frame, a lifting machine for lifting rail transit water pumps, multiple wing rods, and multiple electric push rods.
[0008] The bottom end of the transport frame is rotatably connected to multiple casters at intervals; the bottom end of the gantry frame is fixed to the top end of the transport frame; the fixed part of the lifting machine is fixed to the top end of the gantry frame and its lifting part reciprocates along the height direction; the rail transit water pump is detachably hooked onto the lifting part of the lifting machine to reciprocate along the height direction with the lifting part of the lifting machine; multiple wing rods are arranged parallel to the transport frame and distributed at intervals along the circumference of the transport frame, and one end of each wing rod rotates about the height direction on the outer periphery of the transport frame to unscrew the wing rods on the outer periphery of the transport frame; the fixed ends of multiple electric push rods are respectively fixed to the bottom ends of the multiple wing rods and their pushing ends reciprocate along the height direction to push the transport frame upward to a predetermined height before the rail transit water pump is lifted, so that the multiple casters are disengaged from the ground.
[0009] The beneficial effects of this utility model are: by changing the structure of the rail transit water pump handling device, the gantry frame is first moved to the predetermined position by the handling frame, and then multiple wing rods are rotated on the outer periphery of the handling frame. Since the lifting machine is fixed on the gantry frame and the electric push rod is fixed on the wing rod, the height of the handling frame, casters and gantry frame can be raised before the lifting machine lifts the rail transit water pump, making the handling device more stable and preventing the handling device and rail transit water pump from tipping over.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the transport frame includes a movable frame, a support plate, and multiple connectors. The movable frame includes a first rod, a second rod, a third rod, and a fourth rod arranged horizontally. The first rod and the second rod are arranged parallel to each other at intervals. The two ends of the third rod are respectively fixed to the opposite ends of the first rod and the second rod, defining an insertion area between the first rod, the second rod, and the third rod. One end of the fourth rod rotates about its height axis at the other end of the first rod, and its other end is detachably connected to the other end of the second rod, so that before the other end of the fourth rod is connected to the other end of the second rod... The movable frame is slid to the outer periphery of the rail transit water pump; the support plate is detachably inserted into the insertion area so that after the lifting machine lifts the rail transit water pump, the support plate is inserted into the insertion area to facilitate support for the movement of the rail transit water pump after it has been lowered; multiple connecting pieces are fixed to the outer periphery of the first rod, the second rod, and the third rod; multiple universal wheels are rotatably connected to the bottom ends of the first rod, the second rod, and the third rod at intervals; the bottom end of the gantry frame is fixed to the top ends of the first rod and the second rod; one end of multiple wing rods is rotatably connected to multiple connecting pieces respectively.
[0012] The further beneficial effects of adopting the above are:
[0013] 1. By rotatably connecting one end of the fourth rod to the other end of the first rod, and since the other end of the fourth rod is detachably connected to the other end of the second rod, the insertion area can be opened or closed, which facilitates the insertion of the support plate into the insertion area and restricts the support plate from leaving the insertion area.
[0014] 2. Before connecting the other end of the fourth rod to the other end of the second rod, first slide the moving frame to the outer periphery of the rail transit water pump. After the rail transit water pump is raised, the support plate can be detachably inserted into the insertion area. The rail transit water pump can be placed on the support plate, which facilitates safe and powerless transportation of the rail transit water pump.
[0015] Furthermore, the transport also includes multiple positioning pins, and each of the multiple wing rods is provided with positioning holes arranged along the height direction; the connecting member includes a first connecting strip plate and a second connecting strip plate integrally connected and arranged in an L-shape, and the connection between the corresponding first connecting strip plate and the second connecting strip plate is fixed to the outer periphery of the opposite first rod body, the second rod body or the third rod body, and each of the first connecting strip plate and the second connecting strip plate is provided with a limiting hole that can be arranged opposite to the positioning hole; one end of each of the multiple wing rods is rotatably connected to the connection between the corresponding first connecting strip plate and the second connecting strip plate; the multiple positioning pins are detachably inserted into the oppositely arranged limiting hole and the positioning hole to restrict the open or retracted position of the multiple wing rods.
[0016] The further beneficial effect of adopting the above is that by using multiple positioning pins that can be detachably inserted into the relatively arranged limiting holes and positioning holes, the multiple wing rods can be restricted from rotating or retracting on the outer periphery of the transport frame, thereby improving the stability of the transport device in transporting or lifting the rail transit water pump.
[0017] Furthermore, the first rod and the second rod each have a sliding groove arranged along their length on their opposite rod walls; the opposite sides of the support plate are slidably connected in the two sliding grooves respectively.
[0018] The further beneficial effect of adopting the above is that by utilizing the opposite sides of the support plate to slide in two grooves respectively, the stability of the connection between the support plate and the moving frame can be improved.
[0019] Furthermore, the gantry frame includes two fixed cylinders, two movable rods, multiple limiting pins, and a crossbeam. The two fixed cylinders are arranged along the height direction and their bottom ends are respectively fixed to the top of the transport frame. The cylinder walls of the two fixed cylinders are provided with limiting holes spaced apart along their axial direction. The two movable rods slide within the two fixed cylinders respectively, and their rod walls are provided with multiple pin holes that can be arranged opposite to the multiple limiting holes. The multiple limiting pins are detachably inserted into the oppositely arranged limiting holes and pin holes to limit the lifting position of the two movable rods. The crossbeam is arranged horizontally and its two ends are respectively fixed to the top ends of the two movable rods. The lifting mechanism is fixed to the crossbeam.
[0020] The further beneficial effect of adopting the above is that by using the movable rod to slide up and down inside the fixed cylinder, and since multiple limiting pins can be detachably inserted into the relatively arranged limiting holes and pin holes, the height of the movable rod extending out of the fixed cylinder can be changed to adapt to lifting rail transit water pumps of different shapes.
[0021] Furthermore, the gantry frame also includes two handrails, which are respectively fixed to the outer walls of the two fixed cylinders.
[0022] Furthermore, the lifting machine is an electric hoist, the housing of the electric hoist is the fixed part of the lifting machine and is fixed to the top of the gantry frame, and the lifting hook of the electric hoist is the lifting part; the rail transit water pump can be detachably hooked onto the lifting hook.
