[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 to 5 , this embodiment provides a chain support structure, including: a frame 100, a track 200, a chain 300, a driving mechanism 400 and a support structure 500.

[0032] The frame 100 is composed of a mounting base plate 110, a left side plate 120 and a right side plate 130. The frame 100 is connected to the main body of a skid, a slide plate, a lifting appliance or other workbench through the mounting base plate 110. The left side plate 120 and the right side plate 130 are used for mounting the track 200 and bearing the entire support structure.

[0033] The track 200 is installed between the left side plate 120 and the right side plate 130 of the frame 100. The track 200 includes a horizontally connected section 210, an arc section 220, and a vertically connected section 230. The track is used to carry the chain 300 and limit the chain 300.

[0034] The chain 300 passes through the track 200, enters from the horizontal section 210, passes through the arc section 220, extends out from the vertical section 230, and extends vertically upward.

[0035] The chain 300 includes multiple chain links connected in sequence. Two inner chain plates 310 are used to connect adjacent two chain links. Each chain link includes two support chain plates 320, a pin shaft 330, a connecting rod 340, and a support wheel 350. The two support chain plates 320 are symmetrically arranged at intervals. There are two pin shafts 330. The two pin shafts 330 vertically pass through the two support chain plates 320 to connect the two support chain plates 320. The connecting rod 340 vertically passes through the two support chain plates 320. The support wheel 350 is sleeved in the middle of the connecting rod 340. The positions where the pin shaft 330 and the connecting rod 340 pass through the support chain plate 320 are respectively located on both sides of the horizontal center line of the support chain plate 320. The two inner chain plates 310 are arranged between the two support chain plates 320 and are symmetrically distributed on both sides of the support wheel 350. The two ends of the inner chain plate 310 are respectively hinged to the connecting rod 340 of adjacent two chain links.

[0036] In this embodiment, the inner chain plate 310 is divided into two sections in its length direction. The sections at the same end of the two inner chain plates 310 are offset in the direction of approaching each other, and the offset distance is not less than the thickness of the inner chain plate 310. Such a design can ensure that the inner chain plate 310 does not interfere with the position when connecting adjacent two chain links.

[0037] A raised point 321 is arranged on the top edge of the support chain plate 320. A groove 322 that cooperates with the raised point 321 is arranged at the position corresponding to the raised point 321 on the bottom edge of the support chain plate 320, and the raised point 321 is inclined towards the side close to the connecting rod 340. When the chain 300 is in a vertical state, the support chain plates 320 of adjacent two chain links are in contact. The bottom edge of the upper support chain plate 320 is in contact with the top edge of the lower support chain plate 320. The raised point 321 on the top edge of the lower support chain plate 320 is stuck into the groove 322 on the bottom edge of the upper support chain plate 320, which can make the combination of the two chain links more stable and increase the stability of the chain 300.

[0038] Through the above structural design, the chain 300 can be limited in two directions, X and Y, in the vertical state, so as to bear the vertical load without bending.

[0039] The drive mechanism 400 includes a sprocket 410 and a power unit 420. The sprocket 410 is meshed with the chain 300. The power unit 420 is installed on the frame 100 and can be a combination of a motor and a reducer, or other power sources. The power unit 420 drives the sprocket 410 to rotate through a transmission shaft.

[0040] The support structure 500 includes a support plate 510 for supporting the workpiece. The support plate 510 is arranged on two support chain plates 320 at the top of the chain 300. The support plate 510 can be a flat plate type, a fulcrum type, or a design that imitates the shape of the supported workpiece, etc. A positioning pin 520 and / or a limiting groove are also arranged on the support plate 510 to realize the positioning and support of the workpiece.

[0041] The working principle of a chain support structure provided in this embodiment:

[0042] The entire support structure is installed on the main body of a skid, a slide plate, a lifting tool, or other workbench through the frame 100. The power unit 420 provides rotational power to drive the sprocket 410 to rotate. The sprocket 410 is meshed with the chain 300 to drive the chain 300 to run. Under the limitation of the track 200, the chain 300 realizes the lifting function. The support structure 500 arranged at the top of the chain 300 can realize the function of supporting the workpiece.
