AI Technical Summary
Existing electric chain hoists are prone to derailment of the traveling wheels and tracks during operation, causing the equipment to fall and posing a safety hazard.
By setting a sliding seat on the electric hoist housing, the sliding seat is composed of a sliding plate, pulleys and connecting shaft. Combined with the sliding groove and sliding part on the fixed frame, multiple rollers and sliding parts slide on the fixed frame to ensure the stability of the electric hoist. The sliding seat is driven by a split gearbox and control motor.
This improves the stability of the electric chain hoist, prevents the equipment from falling during operation, and enhances safety.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electric hoist technology, and specifically relates to a chain electric hoist. Background Technology
[0002] An electric chain hoist is a lightweight lifting device consisting of a motor, transmission mechanism, and sprockets. Structural features of the electric chain hoist include: a high-strength tensile shell or die-cast aluminum shell, precision-manufactured using a thin-wall extrusion molding process, resulting in a small size, light weight, and high strength.
[0003] Existing electric hoists mainly move by having their traveling wheels slide within a track. During this movement, the traveling wheels may derail from the track, causing the electric hoist to fall and resulting in a production accident. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a chain electric hoist with good stability.
[0005] The objective of this utility model can be achieved through the following technical solution: A chain electric hoist, characterized in that it includes an electric hoist housing, a gearbox, a brake valve assembly, an electrical control box, a chain, and a drive motor. The gearbox and the electrical control box are both located at the front end of the electric hoist housing, and the drive motor is located at the rear end of the electric hoist housing. A fixed seat is provided at the upper end of the electric hoist housing, and a fixed frame is provided at the upper end of the electric hoist housing. The electric hoist housing slides on the fixed frame via a sliding seat, and the fixed seat and the sliding seat are fixedly connected. The sliding seat consists of upper and lower sliding plates, four pulleys, and a connecting shaft. The left and right sides of the fixed frame have grooves that cooperate with the pulleys and allow them to slide. The upper and lower sliding plates are connected by a connecting shaft, and the four pulleys are rotatably mounted on the connecting shaft. Two sliding parts are provided at the lower end of the sliding plate located at the upper end of the sliding seat, and the upper end of the fixed frame has a sliding groove for the two sliding parts to extend into and slide.
[0006] In the aforementioned electric chain hoist, the gearbox is a split structure, consisting of a front gearbox body, a rear gearbox body, and gear assemblies. The front gearbox body is fixedly connected to the rear gearbox body by fixing bolts.
[0007] In the aforementioned electric chain hoist, the sliding seat is movably connected to the fixed frame via a screw, and a control motor for driving the sliding seat to slide back and forth is provided at the rear end of the sliding seat.
[0008] Compared with existing technologies, this electric chain hoist is more stable during use by fixing the hoist housing to the sliding seat of the fixed frame and positioning it on the fixed frame through multiple rollers and sliding parts. Attached Figure Description

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0014] like Figure 1 , Figure 2 , Figure 3 As shown, this electric chain hoist includes an electric hoist housing 1, a gearbox 2, a brake valve assembly, an electrical control box 3, a chain 4, and a drive motor 5. The brake valve assembly is located inside the gearbox 2 and can control the gear assembly inside the gearbox 2. The gearbox 2 and the electrical control box 3 are both located at the front end of the electric hoist housing 1, and the drive motor 5 is located at the rear end of the electric hoist housing 1. A fixed seat 6 is provided at the upper end of the electric hoist housing 1, and a fixed frame 7 is provided at the upper end of the electric hoist housing 1. The electric hoist housing 1 is mounted on the fixed frame 7 via a sliding seat 8. The sliding seat 8 is fixedly connected to the fixed seat 6. The sliding seat 8 consists of upper and lower sliding plates 9, four pulleys 10 and a connecting shaft 11. The left and right sides of the fixed frame 7 are provided with sliding grooves that cooperate with the pulleys 10 and allow them to slide. The upper and lower sliding plates 9 are connected by the connecting shaft 11, and the four pulleys 10 are rolled on the connecting shaft 11. Two sliding parts 12 are provided on the lower end of the sliding plate 9 at the upper end of the sliding seat 8. The upper end of the fixed frame 7 is provided with a sliding groove for the two sliding parts 12 to extend into and slide.
[0015] To elaborate further, when the electric chain hoist slides, the four pulleys 10 slide in the grooves on the left and right sides, the sliding part 12 at the upper end of the sliding seat 8 slides in the sliding groove, and the electric chain hoist moves on the fixed frame 7 through the screw 13. Compared with existing electric hoists, the operation is more stable.
[0016] To elaborate further, the gearbox 2 is a split structure, consisting of a front gearbox 15, a rear gearbox 16, and a gear assembly. The front gearbox 15 is fixedly connected to the rear gearbox 2 by fixing bolts.
[0017] To elaborate further, the sliding seat 8 is movably connected to the fixed frame 7 via a screw 13, and a control motor 14 for driving the sliding seat 8 to slide back and forth is provided at the rear end of the sliding seat 8.
[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0019] Although this document frequently uses terms such as electric hoist housing 1, gearbox 2, electrical control box 3, chain 4, drive motor 5, fixed base 6, fixed frame 7, sliding seat 8, sliding plate 9, pulley 10, connecting shaft 11, sliding part 12, screw 13, control motor 14, front gearbox 15, and rear gearbox 16, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
