Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and particularly to a hoisting equipment with a rotatable workpiece. Background Technique

[0002] The hoisting equipment is a lifting device for workpieces realized by a gantry structure, which enables the workpiece to move forward, backward, left, right, up and down, and moves the workpiece to an ideal position. With the diversification of industries, people have various functional requirements for hoisting equipment, and the traditional gantry hoisting device can no longer meet people's usage needs. The existing gantry crane device has certain limitations in use. For example, when hoisting a workpiece, the workpiece always remains fixed on the gantry steel cable or fixing piece and cannot rotate the workpiece. When installing and repairing the workpiece, it is often in a hoisting state. At this time, it is necessary to rotate the workpiece to adjust the installation and repair position to facilitate the operation of the staff. Summary of the Invention

[0003] The purpose of the present invention is to provide a hoisting equipment with a rotatable workpiece to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A hoisting equipment with a rotatable workpiece, including two sets of first gantry rails that move back and forth and two sets of second gantry rails that move left and right. The first gantry rails are connected with four sets of first drive motors that drive them to move back and forth, and the second gantry rails are connected with four sets of second drive motors that drive them to move left and right;

[0005] The bottom of the second drive motor is fixedly connected with four sets of hydraulic cylinders that control the up and down movement. The output ends of the four sets of hydraulic cylinders are connected with two sets of rotation modules through a connection component. A workpiece to be hoisted is fixedly connected between the two sets of rotation modules. The first drive motor drives the first gantry rail to drive the second gantry rail, the second drive motor and the hydraulic cylinders to move back and forth. The second drive motor drives the hydraulic cylinders left and right, and the hydraulic cylinders drive the workpiece to be hoisted to be lifted.

[0006] Further, the connection component is linked by a positioning support pin and a transition piece through a first bolt. The transition piece is linked to a connecting piece, the connecting piece is fixed on a hydraulic cylinder connecting piece, the hydraulic cylinder connecting piece is on the hydraulic cylinder through a second bolt, and the housing fixing piece on the hydraulic cylinder is not installed.

[0007] Further, the hydraulic cylinder aligns with the hoisting positioning hole of the workpiece through the positioning support pin to lift the hoisted workpiece. When the equipment is not assembled with the rotation module, it can only move the hoisted workpiece back and forth, left and right, up and down to lift it to a specified position and height.

[0008] Further, when the hoisted workpiece reaches the designated position, the rotation module starts to be assembled. The rotation module consists of a support shell, a support ring, a driven gear, support rollers, a main gear drive motor plate, a main gear, a main gear reducer, and a main gear drive motor. The support ring is composed of two semi-circles and is connected to each other by bolts. The bolts are fixed on the support shell, and the outer shell fixing part is installed on the support shell through the third bolt. Then, the transition part is disassembled to make the positioning support pin independent from the connecting part.

[0009] Further, after the rotation module is assembled, the main gear drive motor drives the main gear reducer and the main gear. The main gear meshes with the driven gear, so that the driven gear also starts to rotate. The driven gear is fixed to the support ring by bolts, and the support ring is fixed to the hoisted workpiece through the positioning support pin and the hole-shaft fit, so that the hoisted workpiece rotates to the designated angle by itself.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] This kind of equipment uses a rotation module outside the hoisted workpiece, and only uses the original hole-shaft fit connection for support, avoiding the reprocessing damage to the hoisted workpiece caused by rotating the hoisted workpiece, and also meeting the requirement of the hoisted workpiece for the hoisting rotation angle position.

Detailed Embodiments

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the terms "bottom" and "top", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0018] Please refer to Figures 1-4 , the present invention provides a technical solution: a hoisting device with a rotatable workpiece, including two sets of first gantry rails 100 that move back and forth and two sets of second gantry rails 300 that move left and right. The first gantry rails 100 are connected with four sets of first drive motors 200 that drive them to move back and forth, and the second gantry rails 300 are connected with four sets of second drive motors 400 that drive them to move left and right;

[0019] At the bottom of the second drive motor 400, four sets of hydraulic cylinders 500 for controlling the up and down movement are fixedly connected. The output ends of the four sets of hydraulic cylinders 500 are connected with two sets of rotating modules 600 through a connecting component 800. A workpiece 700 to be hoisted is fixedly connected between the two sets of rotating modules 600. The first drive motor 200 drives the first gantry rails 100 to drive the second gantry rails 300, the second drive motors 400 and the hydraulic cylinders 500 to move back and forth. The second drive motor 400 drives the hydraulic cylinders 500 left and right, and the hydraulic cylinders 500 drive the workpiece 700 to be hoisted to be lifted.

[0020] The connecting component 800 is linked by a positioning support pin 801 and a transition piece 802 through a first bolt 807. The transition piece 802 is linked to a connecting piece 803, and the connecting piece 803 is fixed on a hydraulic cylinder connecting piece 804. The hydraulic cylinder connecting piece 804 is fixed on the hydraulic cylinder 500 through a second bolt 808, and the housing fixing piece 805 on the hydraulic cylinder 500 is not installed.

[0021] The hydraulic cylinder 500 aligns with the hoisting positioning hole 806 of the workpiece through the positioning support pin 801 to lift the workpiece 700 to be hoisted. When the device does not assemble the rotating module 600, it can only move the workpiece 700 to be hoisted to a specified position and height by moving back and forth, left and right, up and down.

[0022] When the workpiece 700 to be hoisted reaches the specified position, the rotating module 600 is assembled. The rotating module 600 includes a support shell 601, a support ring 602, a driven gear 603, support rollers 604, a main gear drive motor plate 605, a main gear 606, a main gear reducer 607 and a main gear drive motor 608. The support ring 602 is composed of two semi-circles and is linked to each other by bolts. The bolts are fixed on the support shell 601, and the housing fixing piece 805 is installed on the support shell 601 through a third bolt 809. Then, the transition piece 802 is disassembled to make the positioning support pin 801 and the connecting piece 803 independent.

[0023] After the rotation module 600 is assembled, the main gear drive motor 608 starts to drive the main gear reducer 607 and the main gear 606. The main gear 606 meshes with the driven gear 603, so that the driven gear 603 also starts to rotate. The driven gear 603 is fixed to the support ring 602 by bolts, and the support ring 602 is fixedly engaged with the hole and shaft of the workpiece 700 to be hoisted through the positioning support pin 801, so that the workpiece 700 to be hoisted rotates to the specified angle by self-rotation.

[0024] Working principle: The specific use steps of this kind of equipment are as follows: Rigid hydraulic cylinders 500 are used for hoisting up and down. The hydraulic cylinders 500 are connected to the workpiece 700 to be hoisted through the detachable connectors 803. At this time, the connectors 803 and the workpiece 700 to be hoisted form a hole and shaft fit. When the workpiece 700 to be hoisted is lifted, only the connectors 803 are in contact with the workpiece 700 to be hoisted. When the workpiece 700 to be hoisted is moved to the specified position, the staff assembles the rotation module 600 onto the workpiece 700 to be hoisted. At this time, by disassembling the connectors 803, the force on the workpiece 700 to be hoisted is transferred to the rotation module 600, and the original hole and shaft fit of the workpiece 700 to be hoisted is connected to the rotation module 600. The motor that drives the rotation module 600 is actuated, so that the rotation module 600 can also rotate through gear meshing. At this time, the entire workpiece 700 to be hoisted will also rotate accordingly, reaching the required parking angle of the workpiece 700 to be hoisted.

[0025] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
