Description

Technical Field

[0001] This utility model relates to the field of sealing mechanism technology, specifically to an automatic guide device for a handcart. Background Technology

[0002] The partition plate used in existing high-voltage complete sets of equipment is a component that separates the truck compartment from the front lower compartment of the switchgear and installs a friction grounding busbar. The truck chassis is a movable electrical device, located above the partition plate.

[0003] The trolley chassis moves forward along the trolley guide rail inside the switchgear via rollers, thus pushing it into the cabinet. It is then locked to the cabinet by a position lock. When the trolley is moved, the transfer trolley is first locked to the switchgear, then the trolley position lock is released, and the trolley is moved out onto the transfer trolley, thus removing the trolley. During this process, to facilitate trolley transfer, the width of the trolley guide rail is greater than the width of the chassis, leaving a margin. Therefore, the trolley chassis will deflect left and right during the process of rocking the trolley into the working position. With the trend towards electrification and intelligence in switchgear products, electric rocking in and out of the trolley has become standard. During electric rocking, the left and right deflection of the trolley can cause excessive meshing force between the moving and stationary contacts, often exceeding the working limit of the electric rocking, leading to electric disengagement. This process is repeated until electric rocking is achieved. Currently, there is no specific device or measure to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an automatic guide device for circuit breaker trolleys used in high-voltage complete sets of equipment. The device is simple in structure, easy to install, and can realize directional control during the rocking process of circuit breaker trolleys.

[0005] This utility model is achieved through the following technical solution: providing an automatic guide device for a handcart, including a handcart chassis, a switch cabinet, and a partition plate fixed inside the switch cabinet. It also includes two parallel side guide rail assemblies fixed inside the switch cabinet. Two side wheels that travel on the side guide rail assemblies are axled on each side of the handcart chassis. Two bottom guide wheels arranged in a front-to-back pattern are axled on the bottom surface of the handcart chassis. The partition plate is provided with guide grooves that are adapted to the bottom guide wheels.

[0006] In this design, when the handcart chassis is pushed in, the side travel wheels on both sides of the handcart chassis travel on the side guide rail assembly, and the bottom guide wheel at the bottom is guided in the guide groove. This ensures that the handcart is pushed into the working position strictly according to the guide groove, and there is no more left or right deviation, thus ensuring the reliability of the electric rocking. During the removal of the handcart, it is also pushed out in the same direction, reducing the tension of the release. After being moved onto the transfer car, it ensures that the inner handcart is in the center, thus improving the safety of the transfer and collection.

[0007] As an optimization, the side-mounted wheels are single-sided grooved wheels. This allows for a certain degree of guidance during movement.

[0008] As an optimization, the side guide rail assembly includes a mounting plate and a lower support plate extending to one side from the lower end of the mounting plate, as well as an upper plate fixed to the side of the mounting plate and an upper baffle extending to one side from the lower end of the upper plate. The side travel wheel is located between the upper baffle and the lower support plate. In this solution, the lower support plate and the upper baffle form the travel channel for the side travel wheel, providing both travel support and guidance.

[0009] As an optimization, the rear end of the upper upright plate is provided with a limiting part extending downward to the space between the upper baffle and the lower support plate. The limiting part in this design effectively restricts the movement of the side-mounted wheels after they enter the switch cabinet.

[0010] As an optimization, the partition plate has front-to-back extending mounting slots, and a U-shaped plate with an upper opening is detachably fixed inside the mounting slots. A guide groove is formed inside the U-shaped plate. In this design, the U-shaped plate realizes the guide groove.

[0011] As an optimization, the upper end of the U-shaped plate extends to both sides with mounting flanges, which are fixed to the central partition plate by bolts. The mounting flanges in this design enable the installation of the U-shaped plate.

[0012] As an optimization, the pivot of the bottom guide wheel extends vertically, and the pivot of the side walking wheels extends horizontally. Thus, the bottom guide wheel achieves a guiding effect, while the side walking wheels provide both walking and guiding functions.

[0013] The beneficial effects of this utility model are as follows: The automatic handcart guiding device of this utility model, which is composed of bottom guide wheels, a middle partition, a U-shaped plate fixed on the middle partition, and side guide rail components, ensures that after the handcart chassis is pushed in, it strictly follows the guide groove to the working position during the handcart's rocking process, without any left or right deviation, thus ensuring the reliability of the electric rocking. During the removal of the handcart, it also exits directly, reducing the tension of the release. After being moved onto the transfer car, it ensures that the inner handcart is in the center, thus improving the safety of the transfer and collection of the handcart. Attached Figure Description

[0025] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] like Figures 1-9 As shown, the present invention provides an automatic guide device for handcarts, including a handcart chassis 5, a switch cabinet 1, and a partition 3 fixedly connected inside the switch cabinet 1. The partition 3 is horizontally arranged inside the switch cabinet 1, and the handcart compartment is located above the partition 3. The handcart chassis 5 enters and exits the handcart compartment.

[0027] It also includes two parallel side guide rail assemblies 2 fixed inside the switchgear 1. Each side of the trolley chassis 5 has two side wheels 6 that travel on the side guide rail assemblies 2, and the axles of the side wheels 6 extend to the left and right. Each side guide rail assembly 2 corresponds to two side wheels 6, thus enabling the trolley chassis 5 to move in and out of the switchgear.

[0028] The side guide rail assembly 2 includes a mounting plate 21 and a lower support plate 22 extending from the lower end of the mounting plate 21 to one side. The mounting plate 21 and the lower support plate 22 are L-shaped plates formed by bending together. The mounting plate 21 is set vertically and the lower support plate 22 is set horizontally. The mounting plate 21 is fixed inside the switch cabinet 1 by bolts.

[0029] The left and right side guide rail assemblies 2 are symmetrically arranged.

[0030] It also includes an upper plate 23 fixed to the side of the mounting plate 21 and an upper baffle 24 extending from the lower end of the upper plate 23 to one side. The upper plate 23 and the upper baffle 24 are L-shaped plates formed by bending together. The upper plate 23 is set vertically and the upper baffle 24 is set horizontally. The upper plate 23 is welded to the mounting plate 21 or connected by bolts.

[0031] The upper baffle 24 is located above the lower support plate 22, and the side walking wheel 6 is located between the upper baffle 24 and the lower support plate 22. The side walking wheel 6 is a single-sided grooved wheel, which can achieve a certain guiding function during walking.

[0032] The upper plate 23 has a limiting part 25 extending downward to the space between the upper baffle 24 and the lower support plate 22 at its rear end. In this embodiment, the limiting part 25 is used to limit the movement of the side walking wheel 6 after it has moved into position.

[0033] To improve the guiding effect, the bottom surface of the handcart chassis 5 is axled with two bottom guide wheels 7 arranged in a front-to-back pattern. The rotating shaft of the bottom guide wheel 7 extends vertically, and the middle partition 3 is provided with a guide groove 4 that matches the bottom guide wheel 7. Therefore, when the handcart chassis 5 is rocked in and out, the guiding effect of the bottom guide wheel 7 in the guide groove 4 is achieved to guide the handcart chassis 5.

[0034] To realize the guide groove 4, in this embodiment, a mounting groove extending front and rear is opened on the partition plate 3. The mounting groove is a cut rectangular opening.

[0035] The mounting slot has a U-shaped plate 8 with an upper opening that can be detachably fixed. In this embodiment, the upper end of the U-shaped plate 8 has mounting flanges 9 extending to both sides. The mounting flanges 9 are fixed to the middle partition plate 3 by bolts, thereby realizing the detachable fixing of the U-shaped plate 8.

[0036] The U-shaped plate 8 forms a guide groove 4, which is used to guide the bottom guide wheel 7.

[0037] How to use this utility model:

[0038] When the handcart chassis 5 is rocked in, it is first placed on the transfer car, the side travel wheels 6 are aligned with the end of the side guide rail assembly 2, and then it is rocked in, so that the side travel wheels 6 travel on the side guide rail assembly 2. The bottom guide wheel 7 at the bottom is guided in the guide groove 4, so that it is rocked in strictly according to the guide groove 4 to the working position, and no more left or right deviation occurs, which ensures the reliability of electric rocking. During the removal of the handcart, it is also exited in the same way, which reduces the tension of release. After being moved to the transfer car, it is ensured that the inner handcart is in the center, which improves the safety of transfer and collection.
