Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, and more specifically, to a hoisting device for a screening device. Background Art

[0002] A screening device refers to a mechanical device used for classifying the particle sizes of solid materials, and is widely used in multiple industries such as mining, metallurgy, chemical industry, building materials, medicine, and food. Its main function is to separate materials of different particle sizes through the aperture size of a sieve mesh or sieve surface.

[0003] The screening device is usually arranged on the ground. Although shock-absorbing devices are provided at the bottom of the screening device, the shock-absorbing ability is limited, and part of the shock force will still be transmitted to the surrounding environment or structure, which not only increases the impact on the structure and surrounding equipment, but also generates resonance problems, increases the generation of noise, and at the same time has low structural flexibility and cannot be integrated into different production line configurations.

[0004] Although there are many hoisting devices on the market that can be applied to screening devices, such as the Chinese patent with the application number 201720795004.2, which discloses a hanging bracket, the structure includes a frame body, a bottom plate, eight second support rods, and two third support rods. The frame body is a rectangular parallelepiped-shaped frame composed of 12 first support rods. The bottom plate is horizontally and fixedly installed on the bottom surface of the rectangular parallelepiped for carrying the goods inside the hanging bracket; a support plate is fixedly installed at the middle position of each first support rod located in the front and back of the rectangular parallelepiped, and the support plate is parallel to the front and back; among the front and back of the rectangular parallelepiped, the two support plates of each adjacent edge are respectively fixedly installed at both ends of a second support rod; the two third support rods cross, and both ends of each third support rod are respectively fixedly installed at two opposite corners of the top surface of the rectangular parallelepiped; at least 4 lifting lugs are fixedly installed on the first support rod located on the top surface of the rectangular parallelepiped. Although this hanging bracket can be applied to screening devices, different screening devices have different heights, and this device uses a fixed connection method and cannot adapt to different screening devices, which has limitations. At the same time, when the screening device is working in a vibrating state, part of the vibration will be transmitted to the bracket, and there will be a situation where the lifting lug contacts the connecting piece to generate noise.

[0005] Therefore, it is very necessary to propose a hoisting device for a screening device to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , a hoisting device for a screening device, including an upper fixing frame 101, a lower fixing frame 102 and a connecting rod 103. This hoisting device is used to suspend the screening device. It can not only be integrated at the bottom of other devices to reduce the material conveying links, but also save the floor area. The connecting rod 103 is fixedly connected to the four corners of the lower fixing frame 102. The four corners of the upper fixing frame 101 are sleeved on different connecting rods 103. The center of the upper fixing frame 101 is connected with an upper mounting plate 104. A through hole penetrating the upper fixing frame 101 is opened at the center of the upper mounting plate 104. Specifically, in one embodiment, a magnetic separation device is installed at the bottom of the square mounting plate 106 by bolts, and a screening device is installed at the top of the annular mounting plate 105 by bolts. The discharge pipe at the bottom of the screening device extends into the magnetic separation device. The upper mounting plate 104 is used to connect the discharge pipe of the material device, and the bottom of the pipe extends into the screening device. The lower fixing frame 102 is connected with an annular mounting plate 105 and a square mounting plate 106. The four corners of the top of the upper fixing frame 101 are connected with lifting rings 107, and the lifting rings 107 are used to connect with connecting pieces, so as to suspend the device at the bottom of other devices or buildings;

[0031] Refer to Figure 4 and Figure 5 , mounting grooves 108 for clamping the connecting rod 103 are opened on the four sides of the upper fixing frame 101. The upper fixing frame 101 is sleeved on the connecting rod 103 through the mounting grooves 108, and the clamping part at the end is clamped by bolts, so as to fix the upper fixing frame 101 on the outer wall of the connecting rod 103. The clamping parts on both sides of the mounting groove 108 are connected by bolts. A plurality of through holes are opened at the top of the connecting rod 103. The plurality of through holes facilitate adjusting the connection position between the upper fixing frame 101 and the connecting rod 103. By different positions, the height between the upper fixing frame 101 and the lower fixing frame 102 can be controlled. Bolts are installed in the through holes. A connecting component 109 is sleeved on the top of the connecting rod 103, and the bolts are installed in the connecting component 109. It should be noted that the bolts fix the connecting component 109 in the through holes on the connecting rod 103. At this time, the connecting component 109 is the upper limit when the upper fixing frame 101 moves up and down, and is used to limit the height of the upper fixing frame 101. When the upper fixing frame 101 moves upward, the connecting rod 103 is driven to move upward through the connecting component 109;

[0032] Reference Figure 5 , the connecting component 109 includes a sleeve 110 and a moving block 111. Cavities 112 are formed on both sides of the sleeve 110 for accommodating the up and down movement of the moving block 111. When no bolt is installed, the spring 113 pushes the moving block 111 to be located at the top of the cavity 112. When the connecting rod 103 moves upward, the bolt presses the moving block 111 to move downward. At this time, the rubber strip 114 on the top of the moving block 111 will come into contact with the thread of the bolt, playing a protective role for it. The moving block 111 slides up and down in the cavity 112. A spring 113 is connected between the bottom of the moving block 111 and the cavity 112. The moving block 111 is U-shaped. A rubber strip 114 is connected to the middle recess of the moving block 111. Both the rubber strip 114 and the shock-absorbing rubber pad 115 are made of rubber material. The rubber strip 114 is used to protect the thread of the bolt and prevent hard contact between the bolt and the moving block 111. At the same time, the bolt on the connecting rod 103 presses on the rubber strip 114, and the rubber strip 114 can play a role in reducing the transmission of vibration. The bolt is located in the middle recess of the moving block 111 and presses on the top of the rubber strip 114;

[0033] Reference Figure 5 , a shock-absorbing rubber pad 115 is connected to the bottom of the sleeve 110. The connecting component 109 presses on the top of the upper fixing frame 101 through the shock-absorbing rubber pad 115. The shock-absorbing rubber pad 115 can play a role in reducing the transmission of vibration. The upper fixing frame 101 is located at the bottom of the shock-absorbing rubber pad 115.

[0034] Specifically, reference Figure 5 , card edges 116 are symmetrically arranged at the bottom of the sleeve 110. After the connecting component 109 and the upper fixing frame 101 are connected together, the card edges 116 will be located on both sides of the upper fixing frame 101 and cooperate with the convex blocks 117. The card edges 116 are located on both sides of the upper fixing frame 101. Grooves are formed inside the card edges 116. Convex blocks 117 inserted into the grooves are arranged on both sides of the upper fixing frame 101. The convex blocks 117 and the grooves can strengthen the connection between the connecting component 109 and the upper fixing frame 101 and play a positioning role at the same time.

[0035] Specifically, reference Figure 5 , cover plates 118 are arranged on both sides of the cavity 112. A strip-shaped groove for accommodating the up and down movement of the bolt is arranged on the top of the cover plate 118. The two sides of the top of the moving block 111 are longer than the diameter of the bolt, and the spring 113 at the bottom can also play a role in shock absorption;

[0036] Specifically, when no bolt is installed, the spring 113 pushes the moving block 111 to the topmost position. Since the two sides at the top of the moving block 111 are longer than the diameter of the bolt, the bolt can be smoothly installed into the through hole of the connecting rod 103 through the moving block 111. When the upper fixing frame 101 drives the connecting component 109 to move upward, the spring 113 is compressed. At this time, the rubber strip 114, the spring 113 and the shock-absorbing rubber pad 115 can all play a shock-absorbing role.

[0037] Specifically, referring to Figure 5 , a loosening prevention plate 119 is connected to the cover plate 118. Vertical stripes are provided on the loosening prevention plate 119, which will not affect the up and down movement of the bolt, and can reduce the loosening of the bolt. The head of the bolt and the nut come into contact with the loosening prevention plate 119.

[0038] Specifically, bolt holes for fixation are provided on the upper mounting plate 104, the annular mounting plate 105 and the square mounting plate 106, which are convenient for fixing the iron removal device and the screening device on them.

[0039] In this embodiment, referring to Figure 6 , the iron removal device, the screening device and the material pipeline are fixed to the upper fixing frame 101 and the lower fixing frame 102 by bolts. The lifting ring 107 at the top of the upper fixing frame 101 can be suspended from the bottom of other devices or the building through a connecting piece, reducing the floor area occupied, and at the same time, reducing the material conveying links.

[0040] When installing the upper fixing frame 101 and the connecting rod 103, first pass the connecting rod 103 through the installation groove 108 at the end of the upper fixing frame 101, then put the connecting component 109 on the top of the connecting rod 103. After determining the height of the upper fixing frame 101, pass the bolt through the strip-shaped groove on the cover plate 118 into the through hole on the connecting rod 103 and tighten it. After lifting the upper fixing frame 101 by a lifting device, the upper fixing frame 101 will drive the sleeve 110 to move upward. At this time, the spring 113 between the moving block 111 and the sleeve 110 is compressed. Subsequently, drive the connecting rod 103 and the lower fixing frame 102 to move upward by the bolt, then tighten the bolt at the end of the upper fixing frame 101, and finally suspend the lifting device equipped with the screening device and fix it at the discharge port of other devices to reduce the floor area.

[0041] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
