Description

Technical Field

[0001] This invention relates to the field of subway vehicle technology, and more particularly to a hollow plate lifting and installation device and its usage method. Background Technology

[0002] In the rail transit manufacturing industry, the installation of coupler adapter plates for subway vehicles is relatively difficult due to space constraints in the assembly structure and their excessive weight. The installation location of the coupler adapter plate for subway vehicles is inside the underframe cavity at the end of the car body. Using conventional lifting platform transport vehicles, it is impossible to directly move the adapter plate to the installation position because the lifting vehicle cannot rise to the installation height or get close to the installation surface during the lifting process due to the influence of the nearby car body structure.

[0003] Currently, the pre-installation of the adapter plate requires moving and transporting the adapter plate to a position near the traction beam, and then manually lifting the adapter plate. However, the adapter plate weighs about 50kg, and whether it is lifted from the inside of the traction beam to the installation position or from the outside of the traction beam, at least 3 people are needed to barely complete the work, and the fatigue intensity is high. Summary of the Invention

[0004] To address the aforementioned technical problem that existing installation platforms cannot install coupler adapter plates, this invention provides a hollow plate lifting and installation device and its usage method. The main design of this invention is an installation platform that can directly move and transport components to the mounting base, allowing the components to fit snugly against the mounting base.

[0005] The technical means employed in this invention are as follows:

[0006] A hollow plate lifting and installation device includes a mobile work vehicle, a boom, and a wire rope. A hydraulic cylinder is fixed on the floor plate inside the mobile work vehicle. The upper part of the hydraulic cylinder is connected to a hydraulic rod, which protrudes from the upper surface of the mobile work vehicle and is connected to the middle part of the boom. The rear end of the boom is rotatably connected to the upper part of the rear inner wall of the mobile work vehicle. A first pulley is provided at the front end of the boom. One end of the wire rope is connected to a first pin of a plate clamp, and the other end of the wire rope is fixed to the floor plate inside the mobile work vehicle. A wire rope guide is provided on the front surface of the boom, and a second pulley is provided on the boom behind the wire rope guide. The wire rope starts from the plate clamp, passes through the wire rope guide and the second pulley in sequence, and is then fixed to the floor plate inside the mobile work vehicle.

[0007] Furthermore, the plate clamp includes a first pin, a second pin, a third pin, a fourth pin, a fifth pin, an upper clamping plate, a lower clamping plate, an upper connecting rod, and a lower connecting rod;

[0008] In the vertical direction, the first pin, the second pin, the fourth pin, and the third pin are arranged sequentially from top to bottom, and the fourth pin and the fifth pin are in the same position in the vertical direction;

[0009] In the front-back direction, the first pin, the second pin, the fourth pin, and the fifth pin are arranged sequentially from left to right, and the second pin and the third pin are in the same position in the left-right direction;

[0010] In the inward and outward directions, two upper clamping plates, two lower clamping plates, two upper connecting rods, and two lower connecting rods are arranged sequentially from the outside to the inside;

[0011] The upper part of the upper connecting rod is connected to one end of the first pin, the second pin passes through the middle of the upper connecting rod and then connects to the middle of the upper clamping plate, the third pin passes through the middle of the lower connecting rod and then connects to the middle of the lower clamping plate, the rear end of the upper clamping plate and the rear end of the lower clamping plate are connected by the fifth pin; the front end of the upper clamping plate and the front end of the lower clamping plate form an opening that unfolds forward.

[0012] Furthermore, the mobile work vehicle is equipped with a hydraulic pump, which is connected to the hydraulic cylinder via an oil supply pipe.

[0013] Furthermore, the boom includes a front boom and a rear boom connected by a pin, and the upper end of the hydraulic rod is connected to the middle of the rear boom.

[0014] Furthermore, the steel wire rope is fixed in front of the hydraulic cylinder on the bottom plate inside the mobile work vehicle.

[0015] Furthermore, the front wheels of the mobile work vehicle are fixed wheels, and the rear wheels of the mobile work vehicle are guide wheels.

[0016] Furthermore, it also includes a control box, which is electrically connected to the hydraulic pump and is located on the upper part of the mobile work vehicle.

[0017] Furthermore, it also includes a plate clamp storage box, which is disposed on the upper part of the mobile work vehicle.

[0018] The present invention also provides a method for using the hollow panel lifting and installation device, which is based on the above-mentioned hollow panel lifting and installation device and includes the following steps:

[0019] When lifting pre-installed hollow panels, the operation control box controls the hydraulic pump to inlet and outlet oil, which in turn controls the hydraulic cylinder to move the hydraulic rod up and down, thereby driving the boom to move up and down.

[0020] After the boom moves downward, the wire rope moves downward as well, inserting the plate clamp at the front end of the wire rope into the hollow area of ​​the hollow plate.

[0021] The lifting hydraulic rod and the wire rope drive the plate clamp to lift upward. The plate clamp is subjected to the gravity of the plate. The upper and lower connecting rods rotate around the fifth pin and open, so that the upper and lower clamps separate and abut against the hollow area of ​​the plate. The front end of the plate clamp will open and clamp the plate, control the hydraulic rod to rise, and hoist it to the working position.

[0022] The panels are rotated and assembled at the installation location to complete the installation operation.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] This invention can realize the functions of moving, lifting, and assembling the parts to be installed, so that the parts to be installed can fit into the mounting base through the device, saving the manual lifting operations, improving work efficiency and reducing work fatigue.

[0025] This invention is applicable to confined space conditions. During the fastening and installation process, the device is used for support, saving space and manpower, reducing the difficulty of operation, and avoiding personnel bumps and injuries during the operation.

[0026] The device of this invention is lightweight, easy to install, and widely used. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0038] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention.

A hydraulic cylinder 4 is fixed to the bottom plate inside the mobile work vehicle 1. The upper part of the hydraulic cylinder 4 is connected to a hydraulic rod 5, which protrudes from the upper surface of the mobile work vehicle 1 and is connected to the middle part of the boom 2. The rear end of the boom 2 is rotatably connected to the upper part of the rear inner wall of the mobile work vehicle 1. The boom 2 includes a front boom and a rear boom connected by a pin, and the upper end of the hydraulic rod 5 is connected to the middle part of the rear boom. The front end of the boom 2 is equipped with a first pulley 7. One end of the wire rope 3 is connected to the first pin 601 of the plate clamp 6, and the other end of the wire rope 3 is fixed to the bottom plate inside the mobile work vehicle 1. A wire rope guide 8 is provided on the front surface of the boom 2, and a second pulley 9 is provided on the boom 2 behind the wire rope guide 8. The wire rope 3 starts from the plate clamp 6, passes through the wire rope guide 8 and the second pulley 9 in sequence, and is then fixed to the bottom plate inside the mobile work vehicle 1. The fixed position of the wire rope 3 on the bottom plate inside the mobile work vehicle 1 is located in front of the hydraulic cylinder 4. A hydraulic pump 10 is provided inside the mobile work vehicle 1. The hydraulic pump 10 is connected to the hydraulic cylinder 4 through an oil supply pipe, which is used for oil inlet and outlet.

[0043] The plate clamp 6 includes a first pin 601, a second pin 602, a third pin 603, a fourth pin 604, a fifth pin 609, an upper clamping plate 605, a lower clamping plate 606, an upper connecting rod 607, and a lower connecting rod 608.

[0044] In the vertical direction, the first pin 601, the second pin 602, the fourth pin 604 and the third pin 603 are arranged sequentially from top to bottom, and the fourth pin 604 and the fifth pin 609 are in the same position in the vertical direction.

[0045] In the front-back direction, the first pin 601, the second pin 602, the fourth pin 604 and the fifth pin 609 are arranged from left to right, and the second pin 602 and the third pin 603 are in the same position in the left-right direction;

[0046] In the inward and outward directions, two upper clamping plates 605, two lower clamping plates 606, two upper connecting rods 607, and two lower connecting rods 608 are arranged sequentially from the outside to the inside.

[0047] The upper part of the upper connecting rod 607 is connected to one end of the first pin 601. The second pin 602 passes through the middle of the upper connecting rod 607 and is connected to the middle of the upper clamping plate 605. The third pin 603 passes through the middle of the lower connecting rod 608 and is connected to the middle of the lower clamping plate 606. The rear ends of the upper clamping plate 605 and the rear ends of the lower clamping plate 606 are connected by the fifth pin 609. The front ends of the upper clamping plate 605 and the front ends of the lower clamping plate 606 form an opening that extends forward.

[0048] The control box 13 is electrically connected to the hydraulic pump 10, and the control box 13 is located on the upper part of the mobile work vehicle 1. The plate clamp storage box 14 is located on the upper part of the mobile work vehicle 1.

[0049] When lifting hollow panels (i.e., lifting pre-installed components), operate the buttons on control box 13 to control the hydraulic pump's oil intake and output, which in turn controls the hydraulic cylinder's hydraulic rod to move up and down, thereby driving the boom to move up and down. After the boom moves downward, the wire rope will move downward a significant distance, inserting the plate clamp at the front end of the wire rope into the hollow area of ​​the hollow panel. The hydraulic rod is then raised, and the wire rope pulls the plate clamp upward. The plate clamp, under the weight of the panel, transmits force, causing the upper and lower connecting rods to rotate and open around the pin, separating the upper and lower clamps and pressing against the hollow area of ​​the panel. The front end of the plate clamp will "open," clamping the panel, controlling the hydraulic rod to rise and hoist it to the working position. At the installation position, the panel can be rotated and assembled to complete the installation operation. After the operation is completed, the hydraulic rod is retracted, the plate clamp is removed, and stored in the storage box. Then, the boom's pin can be pulled out, allowing the front of the boom to fold, saving storage space.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
