Description

Technical Field

[0001] This utility model relates to the field of flotation machine equipment protection technology, specifically a nanopolymer protective sleeve for flotation machine fixing bolts. Background Technology

[0002] In the mineral processing industry, flotation machines are key equipment, and their stable operation plays a vital role in the efficiency and safety of the entire production process. The various components of the flotation machine need to work closely together, and the fixing bolts play a crucial role in ensuring the stable connection of each component.

[0003] Traditional protective sleeves are often simply fitted directly onto the outside of the fixing bolts. During the long-term operation of the flotation machine, slight but continuous vibrations are inevitably generated. These vibrations gradually weaken the connection stability between the protective sleeve and the fixing bolts, causing the protective sleeve to loosen or even fall off. Once the protective sleeve falls off, the fixing bolts will be directly exposed to the harsh working environment and are extremely susceptible to corrosion and wear. Summary of the Invention

[0004] The purpose of this invention is to provide a nanopolymer protective sleeve for the fixing bolts of a flotation machine, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0005] This utility model relates to a nanopolymer protective sleeve for flotation machine fixing bolts, comprising:

[0006] Bolt housing;

[0007] The fixing component includes a protective sleeve, a first rubber base pad, a second rubber base pad, a snap-fit ​​block, and a snap-fit ​​groove. The protective sleeve is fitted onto the top of the outer surface of the bolt housing. The first rubber base pad and the second rubber base pad are located at the lower part of the outer surface of the bolt housing. The snap-fit ​​block is fixed at the lower part of both ends of the outer surface of the protective sleeve. The snap-fit ​​groove is opened on the upper part of the first rubber base pad and the second rubber base pad, and the snap-fit ​​block is inserted into the inside of the snap-fit ​​groove.

[0008] Furthermore, the fixing component also includes a side plate, a support rod, a spring, and a positioning frame. The side plate is fixed to one end of the outer surface of the first rubber base pad and the second rubber base pad. The support rod is fixed to one side of the side plate. The spring is wrapped around the outside of the support rod. The positioning frame is fixed to one side of the spring and clamped on both sides of the outer surface of the snap-fit ​​block.

[0009] Furthermore, a pull rod runs through the middle of the side plate, with one side of the pull rod fixed to one side of the positioning frame and a handle fixed to the other side of the pull rod.

[0010] Furthermore, the first rubber pad and the second rubber pad surround the outer surface of the protective casing.

[0011] Furthermore, it also includes a quick-release component, which includes an inner groove and an insert plate. The inner groove is formed at one end of the rubber base pad one, and the insert plate is fixed at one end of the rubber base pad two and inserted into the inner groove.

[0012] Furthermore, support blocks are fixed on both sides of the outer surface of the first rubber pad, and clamping blocks are fixed on both sides of the outer surface of the second rubber pad, with the clamping blocks clamping the top and bottom of the support blocks.

[0013] Furthermore, rubber pillars are bonded to the outer surface of the clamping block, and the rubber pillars block one end of the support block.

[0014] This utility model has the following beneficial effects:

[0015] This invention features a protective sleeve, a rubber base pad, and a second rubber base pad on the outside of the bolt housing. When the operator holds the handle and pulls the positioning frame to both sides, the locking block can smoothly engage with the locking groove. Subsequently, the spring rebound force will tightly clamp the positioning frame on both sides of the outer surface of the locking block. This tight positioning method greatly enhances the connection stability between the protective sleeve and the fixing bolt. The spring force provides a continuous and stable fastening force. When facing the vibration force generated by the long-term operation of the flotation machine, the tight fit between the positioning frame and the locking block can effectively disperse and offset the vibration effect, preventing the protective sleeve from loosening due to vibration.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a nanopolymer protective sleeve for flotation machine fixing bolts, comprising:

[0028] Bolt housing 100;

[0029] The fixing component includes a protective sleeve 200, a first rubber base 201, a second rubber base 202, a snap-fit ​​block 203, and a snap-fit ​​groove 209. The protective sleeve 200 is sleeved on the top of the outer surface of the bolt housing 100. The first rubber base 201 and the second rubber base 202 are disposed on the lower part of the outer surface of the bolt housing 100. The snap-fit ​​block 203 is fixed on the lower part of both ends of the outer surface of the protective sleeve 200. The snap-fit ​​groove 209 is opened on the upper part of the first rubber base 201 and the second rubber base 202. The snap-fit ​​block 203 is inserted into the inside of the snap-fit ​​groove 209.

[0030] Rubber base pad 1 201 and rubber base pad 202 are installed at the bottom of bolt housing 100, while snap-fit ​​block 203 snaps into the inside of snap-fit ​​groove 209, so that the protective sleeve is installed on the outside of bolt housing 100.

[0031] The fixing components also include a side plate 204, a support rod 205, a spring 206, and a positioning frame 210. The side plate 204 is fixed to one end of the outer surface of the first rubber base pad 201 and the second rubber base pad 202. The support rod 205 is fixed to one side of the side plate 204. The spring 206 is wrapped around the outside of the support rod 205. The positioning frame 210 is fixed to one side of the spring 206 and clamped on both sides of the outer surface of the snap-fit ​​block 203.

[0032] The spring force generated by the rebound of spring 206 will cause the positioning frame 210 to be tightly clamped on both sides of the outer surface of the snap block 203. This tight positioning method greatly enhances the connection stability between the protective sleeve and the fixing bolt.

[0033] A pull rod 207 runs through the middle of the side panel 204. One side of the pull rod 207 is fixed to one side of the positioning frame 210, and a handle 208 is fixed to the other side of the pull rod 207.

[0034] Personnel can hold handle 208 and pull the positioning frame 210.

[0035] Rubber base pad 1 201 and rubber base pad 202 surround the outer surface of the protective cover 200.

[0036] Working principle: First, when the protective cover needs to be installed onto the fixing bolt, the operator first grasps the handle 208 and pulls the positioning frame 210 connected to the spring 206 to both sides using the force applied by hand. As the positioning frame 210 moves to both sides, the space originally restricted by the positioning frame 210 is released, allowing the locking block 203 to be aligned and locked into the locking groove 209 set at the corresponding position of the fixing bolt without obstruction. After the locking block 203 is fully locked into the locking groove 209, the operator releases the handle 208. At this time, the spring 206, having lost the tensile force of the external force, begins to rebound due to its own elastic recovery ability. During the rebound process, the elastic potential energy stored in the spring 206 is converted into kinetic energy, driving the positioning frame 210. Moving towards the snap-fit ​​block 203, the positioning frame 210 eventually clamps tightly onto both sides of the outer surface of the snap-fit ​​block 203. The spring force generated by the spring 206 provides a continuous and stable fastening force for this constraint. When the flotation machine is put into long-term operation and inevitably generates slight but continuous vibration, the tight fit between the positioning frame 210 and the snap-fit ​​block 203 can play an excellent role in buffering and dispersing. The vibration force will be transmitted to the positioning frame 210 through the snap-fit ​​block 203, and then dispersed by the positioning frame 210 to the entire protective sleeve structure. The spring force of the spring 206 further offsets part of the vibration effect, ensuring that the connection between the protective sleeve and the fixing bolt remains stable, effectively preventing the protective sleeve from loosening or even falling off due to vibration.

[0037] Please see Figure 1 , Figure 3 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The quick-release component includes an inner groove 300 and an insert plate 301. The inner groove 300 is formed at one end of the rubber base pad 201, and the insert plate 301 is fixed at one end of the rubber base pad 202 and inserted into the inner groove 300.

[0039] When the bolts are fixed to the top of the flotation machine, the rubber pad 1 201 and the rubber pad 2 202 will fit tightly against the surface of the flotation machine, avoiding direct contact between the bottom of the bolts and the flotation machine. The rubber pad 1 201 and the rubber pad 2 202 have unique material properties, and their surfaces have a certain degree of roughness and elasticity, which greatly increases the friction with the surface of the flotation machine.

[0040] Support blocks 302 are fixed on both sides of the outer surface of rubber pad 1 201, and clamping blocks 303 are fixed on both sides of the outer surface of rubber pad 2 202. The clamping blocks 303 are clamped on the top and bottom of the support blocks 302.

[0041] When rubber pad 1 201 and rubber pad 2 202 are joined together, clamping block 303 clamps the top and bottom of support block 302 at the same time, which further reinforces rubber pad 1 201 and rubber pad 2 202.

[0042] A rubber column 304 is bonded to the outer surface of the clamping block 303, and the rubber column 304 blocks one end of the support block 302.

[0043] The working principle is as follows: First, when rubber pad 1 201 and rubber pad 2 202 are joined together, the insert plate 301 is inserted into the inner groove 300, while the clamping block 303 simultaneously clamps the top and bottom of the support block 302, further reinforcing rubber pad 1 201 and rubber pad 2 202. When the bolts are fixed to the top of the flotation machine, rubber pad 1 201 and rubber pad 2 202 will fit tightly against the surface of the flotation machine, avoiding direct contact between the bottom of the bolts and the flotation machine. Rubber pad 1 201 and rubber pad 2 202 have unique material properties, and their surfaces have a certain degree of roughness and elasticity, which greatly increases the friction with the surface of the flotation machine. The roughness of rubber pad 1 201 and rubber pad 2 202 greatly increases the friction with the surface of the flotation machine. This increased friction allows the bolts to be more firmly fixed to the flotation machine after installation. Even under the continuous vibration environment generated by the long-term operation of the flotation machine, it can effectively prevent the bolts from loosening or shifting due to vibration, ensuring the stability of the equipment structure.
