Description

Technical Field

[0001] The utility model relates to the technical field of high and low pressure coolers, in particular to a high and low pressure cooler for mining with stable performance. Background Art

[0002] Mining high and low pressure coolers are heat exchange equipment used in mines. They are mainly used to cool the ore or other minerals in the mine to keep the temperature of the mine within an appropriate range. In the mine, due to the deep underground depth and high ground temperature, heat exchange equipment is needed to reduce the temperature of the mine. High and low pressure coolers are usually composed of high-pressure heat exchangers, low-pressure heat exchangers, fans, water pumps, pipes, etc., and heat is exchanged through circulating water to take away the heat in the mine to achieve the purpose of cooling.

[0003] The existing high and low pressure coolers for mining are very susceptible to collisions by foreign objects when used in the mine due to the influence of the working environment of the mine. After searching, the utility model with the patent number "CN218723468U" provides "a high and low pressure cooler for mining with stable performance, which relates to the technical field of high and low pressure coolers. The high and low pressure cooler for mining with stable performance aims to solve the technical problem that it is not convenient to operate the high and low pressure coolers stably under the existing technology; the high and low pressure cooler for mining includes a high and low pressure cooler body; a positioning assembly is arranged at the bottom end of the high and low pressure cooler body, a support plate is arranged at the bottom end of the positioning assembly, a transmission assembly is arranged at the bottom end of the support plate, the transmission assembly is arranged in multiple groups, a buffer assembly is arranged at the bottom end of the transmission assembly, and the buffer assembly A bottom plate is provided at the bottom end, and mounting pipes are fixedly installed on the outside of the high and low pressure cooler body, and two groups of mounting pipes are provided; the high and low pressure cooler for mining with stable performance only needs to transmit the vibration to the buffer assembly through the transmission assembly when the high and low pressure cooler body vibrates, and the buffering treatment is performed through the setting of the buffer assembly, thereby facilitating the stable operation of the high and low pressure cooler. However, the high and low pressure cooler for mining only weakens the vibration generated by the operation, and the overall shell of the high and low pressure cooler is exposed to the external environment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 As shown, the utility model provides an implementation mode: a high and low pressure cooler for mining with stable performance, comprising a high and low pressure cooler 1, a top guard plate 4 and a side guard plate 5, a shock absorbing base 2 is installed at the lower end of the high and low pressure cooler 1, a fixed base plate 3 is bolted to the upper end of the high and low pressure cooler 1, a top guard plate 4 is elastically installed at the top of the fixed base plate 3, side guard plates 5 are elastically installed on both sides of the fixed base plate 3, and an elastic connector 6 is movably installed between the two groups of side guard plates 5.

[0025] Furthermore, mounting seats 31 are welded on both sides of the upper end of the fixed base plate 3, and a guide groove 311 is opened on the upper surface of the mounting seat 31. A guide block 42 matching the guide groove 311 is welded on the lower end of the top guard plate 4, and the guide block 42 is slidably installed inside the guide groove 311. When the top guard plate 4 is displaced, the guide block 42 at the lower end of the top guard plate 4 will slide in the guide groove 311 to ensure that after the top guard plate 4 is subjected to impact force, the top guard plate 4 will generate a moving force perpendicular to the downward direction of the top guard plate 4.

[0026] Furthermore, side connecting plates 32 are welded on both sides of the mounting seat 31, compression springs 43 are welded on both sides of the upper ends of the side connecting plates 32, and the top ends of the compression springs 43 are welded to the lower surface of the top guard plate 4, and the top guard plate 4 forms an elastic structure with the side connecting plates 32 through the compression springs 43, and a damping rod 44 is installed on the inner side of the two groups of compression springs 43, and the top end of the damping rod 44 is fixedly installed on the lower surface of the top guard plate 4. When the top guard plate 4 produces a displacement change, the compression spring 43 will produce elastic deformation, thereby absorbing and weakening the impact force generated by the collision. At the same time, the damping rod 44 cooperates with the compression spring 43 to absorb the impact force, which can effectively buffer the impact force of the collision from the upper end of the top guard plate 4.

[0027] Furthermore, a vertical plate 33 is welded to the side of the side connecting plate 32 away from the mounting seat 31, and sliding seats 34 are welded to both ends of one side of the vertical plate 33. A slider 52 is welded to the inner side of the side guard plate 5, and the slider 52 is slidably installed inside the sliding seat 34. When the side guard plate 5 is displaced, the slider 52 on the inner side of the side guard plate 5 will slide in the sliding seat 34, ensuring that after the side guard plate 5 is subjected to impact force, the side guard plate 5 will generate a moving force perpendicular to the side guard plate 5.

[0028] Furthermore, compression spring 2 53 is welded on one side of the vertical plate 33 and on both sides of the slide seat 34, and the other end of the compression spring 2 53 is welded to the inner side of the side guard plate 5, and the side guard plate 5 forms an elastic structure through the compression spring 2 53, and a damping rod 2 54 is fixedly installed on one side of the vertical plate 33 and on the inner side of the slide seat 34, and the other end of the damping rod 2 54 is fixedly installed on the inner side of the side guard plate 5. When the side guard plate 5 produces a displacement change, the compression spring 2 53 will produce elastic deformation, thereby absorbing and weakening the impact force generated by the collision. At the same time, the damping rod 2 54 cooperates with the compression spring 2 53 to absorb the impact force, which can effectively buffer the impact force of the collision from the side of the side guard plate 5.

[0029] Furthermore, a top protection pad 41 is bonded to the upper surface of the top guard plate 4, and a side protection pad 51 is bonded to the side surface of the side guard plate 5. Both the top protection pad 41 and the side protection pad 51 can be made of rubber material, which can effectively protect the top guard plate 4 and the side guard plate 5 and extend the service life of the top guard plate 4 and the side guard plate 5.

[0030] Furthermore, the elastic connector 6 includes a sleeve 64, a connecting spring 63, a slide bar 62 and a block 61. The inner ends of the side guard plate 5 are welded with a slot seat 55. The inside of the slot seat 55 is slidably installed with a block 61. The other end of the block 61 is welded with a slide bar 62. The other end of the slide bar 62 is welded with a connecting spring 63, and the connecting spring 63 is located in the middle of the two groups of slide bars 62. The outer side of the slide bar 62 is slidably installed with a sleeve 64, and the connecting spring 63 is installed inside the sleeve 64. When the two side surfaces of the high and low pressure cold exchanger 1 are bumped at the same time, the elastic connector 6 exerts an elastic force, the slide bars 62 on both sides slide in the sleeve 64, and the connecting spring 63 is compressed and deformed, thereby buffering the impact force.

[0031] Working principle: First, a high and low pressure cooler for mining with stable performance is moved to the working position. In the first step, when the high and low pressure cooler 1 is in working state, the vibration generated by the operation of the high and low pressure cooler 1 will be absorbed and buffered by the shock-absorbing base 2. In the second step, when a foreign object hits one of the two side surfaces of the high and low pressure cooler 1, the foreign object will first contact the side pad 51 on the outside of the side guard plate 5. When the impact force is large, the side guard plate 5 will produce an inward displacement change. At this time, the compression spring 2 53 is in a compressed state, and the elastic deformation produced by the damping rod 2 54 and the compression spring 2 53 will buffer the impact force on the outside of the side guard plate 5, effectively protecting the two side surfaces of the high and low pressure cooler 1. In the third step, when the high and low pressure cooler When the two sides of the cooler 1 are bumped at the same time, the elastic connecting member 6 exerts an elastic force, the sliding rods 62 on both sides slide in the sleeve 64, and the connecting spring 63 is compressed and deformed, thereby buffering the impact force. In the fourth step, when a foreign object hits the top of the high and low pressure cooler 1, the foreign object will first contact the top protective pad 41 on the outside of the top guard plate 4. When the impact force is large, the top guard plate 4 will produce a downward displacement change. At this time, the compression spring 43 is in a compressed state, and the elastic deformation produced by the damping rod 44 and the compression spring 43 buffers the impact force on the upper end of the top guard plate 4, effectively protecting the upper end surface of the high and low pressure cooler 1, thus completing the use process of a high and low pressure cooler with stable performance for mining.

[0032] It should be noted that the shock-absorbing base 2 mentioned above is consistent with the (buffer component) structure in the comparative document (CN218723468U), and will not be described in detail herein.
