Technical Field

[0001] The invention belongs to the technical field of lifting workpieces and products, and in particular relates to a track-type mobile lifting equipment. Background Art

[0002] Lifting equipment is commonly used to move workpieces and transfer products during production and operation. In a larger working space, the lifting equipment can use an overhead crane to achieve the up and down movement of the lifted objects and the horizontal movement in the working space, or a crane can be used for lifting. However, for small working spaces, such as small warehouses, an overhead crane cannot be installed. In addition, it is not convenient to use a crane for lifting.

[0026] The structure of the present invention is further described below with reference to the accompanying drawings and by way of examples. It should be noted that the present examples are descriptive rather than restrictive.

[0027] A rail-mounted mobile lifting device, see Figure 1-Figure 6 The invention point is: it includes a linear track 1 and a movable bracket part.

[0028] The linear track adopts a square tube track with a through slot in the middle of the lower end. Connection holes are arranged near the two ends of the two side walls of the linear track, and the linear track can be suspended and fixed at the top position of the working space by passing through connection bolts.

[0029] The movable bracket part includes a plate bracket 2, a connecting seat 3, two groups of movable components, and two groups of positioning components. The plate bracket adopts a plate-shaped structure that is wide at the top and narrow at the bottom and symmetrical at the left and right. A lower connecting hole is provided in the middle part of the plate bracket near the lower end for connecting with the connecting seat. Upper connecting holes are symmetrically provided on the left and right sides of the plate bracket near the upper end for connecting with the two groups of movable components respectively.

[0030] The connecting seat is composed of a base plate 3.2 and two vertical sides 3.1 that are parallel and vertically fixed to the base plate. Coaxial through holes are provided on the two vertical sides. The two vertical plates are fitted with a gap between the lower end of the plate-type bracket. The through holes on the two vertical plates are aligned with the lower connecting holes on the plate-type bracket. A fastening shaft is passed through the lower connecting hole and the through holes on the two vertical plates. A shaft cap is provided at one end of the fastening shaft 4 and an external thread is provided at the other end. A fastening nut 9 is connected to the external thread portion to achieve a fixed connection between the connecting seat and the plate-type bracket. Connecting holes are provided on both sides of the two vertical plates on the connecting seat. Depending on the specific product to be lifted and moved, different forms of lifting tooling can be provided. The upper part of the tooling is fixedly connected to the connecting hole of the connecting seat by bolts, and the lower part of the lifting tooling directly acts on the product.

[0031] The two groups of moving components are used to suspend the moving bracket part as a whole on the linear track in a movable manner along the left and right directions. Both groups of moving components include a moving shaft 8 and two moving rollers 7, and the two moving rollers are preferably bearings. The two moving shafts are respectively fixedly installed in the two upper connecting holes on the plate-shaped bracket in the front and rear directions. Each moving shaft is located at the front and rear sides of the plate-shaped bracket, and a moving roller is rotatably installed.

[0032] The upper part of the plate-type bracket extends into the inner cavity of the linear track through the slot at the lower part of the linear track. The front and rear moving rollers of the two groups of moving components respectively form rolling contact with the inner bottom surface of the linear track located on both sides of the slot. And there is a gap between the front and rear ends of the moving shaft and the inner surface of the front and rear side walls of the linear track respectively. The moving bracket part can be smoothly moved in the left and right directions in the linear track. The setting of the left and right groups of moving components, on the one hand, ensures the load-bearing capacity of the mobile hoisting equipment, and on the other hand, limits its swing in the length direction of the track.

[0033] The two groups of positioning components are used to limit the movement of the movable bracket part in the inner cavity of the track in the width direction to ensure the stability of the mobile lifting equipment. Both groups of positioning components include a positioning vertical shaft 6 and two positioning rollers 5, and the two positioning rollers are preferably bearings. The lower ends 6.1 of the two positioning vertical shafts are fixedly connected to the upper end of the plate-type bracket, and the two positioning vertical shafts are respectively located on the inner sides of the two upper connecting holes. The two positioning rollers are rotatably mounted on the upper and lower parts of the positioning columns. The positioning rollers are arranged in the inner cavity of the linear track, and a clearance fit is formed between the positioning rollers and the front and rear sides of the inner cavity of the linear track, so as to prevent the movable bracket part from moving in the track in the width direction and prevent it from getting stuck during movement.

[0034] In the above structure, the linear track can be formed by processing with a formed pipe.

[0035] When this mobile lifting equipment is in use, a small electric hoist can be configured at the lower end of the connecting seat, which can realize the up and down movement of the product and the translation in the space, and better meet the needs of product transportation in a small space.

[0036] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
