Description

Technical Field

[0001] The utility model relates to the technical field of ground bull hoists, in particular to a guide structure of a ground bull hoist. Background Art

[0002] The Di Niu elevator can achieve smooth lifting and lowering of goods, ensuring that the height of the goods matches the conveyor line when docking. At present, in order to ensure that the cargo platform does not deviate when it is lifted upward, the Di Niu elevator will set a guide structure on the cargo platform frame.

[0003] When the existing guide structure is in use, a rectangular tube is used as a guide rail, and the three guide wheels move vertically up and down along the guide rail. However, since the potential energy of the cargo platform's own weight plus the cargo weight is very large, when driven upward by the chain, the cargo platform frame will produce inward lateral stress, causing the cargo platform frame to shake when sliding on the guide structure and the entire equipment to shake. Therefore, for the sake of industry technological progress, to better ensure that the cargo platform can slide stably and to improve the competitiveness of core technologies, this application proposes a new implementation plan that is different from the guide structure of the cargo platform frame of the bull hoist in the prior art. Utility Model Content

[0004] The utility model aims to solve the problem that the cargo platform frame of the existing bull hoist shakes when sliding on the guide structure and the whole equipment shakes, and proposes a bull hoist guide structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The guide structure of the ground bull hoist includes a cargo platform frame and multiple guide components. The guide components include two main mounting plates. A guide rail is slidably connected between the two main mounting plates. The guide rail is a C-shaped groove structure. The top of the main mounting plate is fixedly connected to a front connecting plate and a side connecting plate. One side of the front connecting plate is connected to a front guide wheel through a rotating shaft. The front guide wheel rolls on the side of the guide rail. One side of the side connecting plate is connected to a side guide wheel through a rotating shaft. The side guide wheel rolls in the C-shaped groove of the guide rail.

[0007] Furthermore, the top and bottom ends of the guide rail are fixedly connected to limit plates.

[0008] Furthermore, two side mounting plates are fixedly connected to one side of the guide rail.

[0009] Furthermore, the main mounting plate is provided with a plurality of mounting holes.

[0010] Furthermore, a reinforcement plate is fixedly connected between the front connecting plate and the main mounting plate and between the side connecting plate and the main mounting plate.

[0011] Furthermore, a rubber pad is bonded to the bottom of the main mounting plate.

[0012] Furthermore, the circumferential outer walls of the front guide wheel and the side guide wheels are sleeved with rubber sleeves, and the circumferential outer walls of the rubber sleeves are provided with anti-slip grooves.

[0013] The beneficial effects of the utility model are:

[0014] 1. By changing the existing rectangular tube as the guide rail to a C-shaped groove as the guide rail, and at the same time reducing the number of guide wheels from three to two, the guide wheels can move vertically in the C-shaped groove, limiting the inward lateral stress of the cargo platform frame and ensuring the smooth operation of the cargo platform.

[0015] 2. The provision of the reinforcement plate can enhance the firmness of the connection between the front connecting plate and the main mounting plate and between the side connecting plate and the main mounting plate.

[0016] 3. The friction between the front guide wheel and the side guide wheel and the guide rail is increased by the rubber sleeve and the anti-skid groove, thereby preventing the front guide wheel and the side guide wheel from slipping. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] Reference Figure 1-Figure 5 The guide structure of the ground bull hoist includes a cargo platform frame 1 and multiple guide components 2. The guide component 2 includes two main mounting plates 201. A guide rail 3 is slidably connected between the two main mounting plates 201. The guide rail 3 is a C-shaped groove structure. A front connecting plate 202 and a side connecting plate 204 are welded to the top of the main mounting plate 201. A front guide wheel 203 is plugged into one side of the front connecting plate 202 through a rotating shaft. The front guide wheel 203 rolls on the side of the guide rail 3. A side guide wheel 205 is plugged into one side of the side connecting plate 204 through a rotating shaft. The side guide wheel 205 rolls in the C-shaped groove of the guide rail 3 and is driven to move on the cargo platform frame 1 through a driving mechanism, so that the side guide wheel 205 moves up and down along the C-shaped groove of the guide rail 3, and at the same time, the front guide wheel 203 moves along the side of the guide rail 3.

[0027] The top and bottom ends of the guide rail 3 are welded with limit plates 4, and the top and bottom ends of the guide rail 3 are limited by the limit plates 4. Two side mounting plates 5 are welded on one side of the guide rail 3. The main mounting plate 201 is provided with multiple mounting holes 6. Bolts are passed through the mounting holes 6 to fix the main mounting plate 201 to the cargo platform frame 1. Reinforcing plates 7 are welded between the front connecting plate 202 and the main mounting plate 201 and between the side connecting plate 204 and the main mounting plate 201, so as to strengthen the firmness of the connection between the front connecting plate 202 and the main mounting plate 201 and between the side connecting plate 204 and the main mounting plate 201.

[0028] The working principle of this embodiment: during installation, first, bolts are passed through the mounting holes 6 to fix the main mounting plate 201 on the cargo platform frame 1, and the side guide wheels 205 are located in the C-shaped groove of the guide rail 3, while the front guide wheels 203 are in contact with the side of the guide rail 3. When in use, the driving mechanism is used to drive the cargo platform frame 1 to move, so that the side guide wheels 205 move up and down along the C-shaped groove of the guide rail 3, while the front guide wheels 203 move along the side of the guide rail 3, thereby achieving the lifting of the goods.

[0029] Example 2

[0030] Reference Figure 6, a deburring device for metal processing machinery manufacturing, also includes a rubber pad 8 bonded to the bottom of the main mounting plate 201, the design of the rubber pad 8 prevents looseness between the main mounting plate 201 and the cargo platform frame 1, thereby ensuring the stability of the guide assembly 2, the circumferential outer wall of the front guide wheel 203 and the side guide wheel 205 is sleeved with a rubber sleeve 9, and the circumferential outer wall of the rubber sleeve 9 is provided with an anti-skid groove 10, which increases the friction between the front guide wheel 203 and the side guide wheel 205 and the guide rail 3 through the rubber sleeve 9 and the anti-skid groove 10, thereby preventing the front guide wheel 203 and the side guide wheel 205 from slipping.

[0031] The working principle of this embodiment is as follows: when in use, the friction between the front guide wheel 203 and the side guide wheel 205 and the guide rail 3 is increased by the rubber sleeve 9 and the anti-slip groove 10, thereby preventing the front guide wheel 203 and the side guide wheel 205 from slipping.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
