Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a tool for disassembling and assembling a compressed air hose in a solenoid valve box. Background Art

[0002] In tobacco processing enterprises, dust removal equipment is used due to the production equipment and workshop environment. At present, tobacco enterprises often use bag filter dust collectors to filter dust-containing gases. The dust is filtered through the filter bags inside the dust collector box, and the filtered air is discharged from the dust collector outlet. The dust attached to the filter bag is controlled by the dust collector control system to control the switch of the solenoid valve, thereby turning on or off the compressed air gap-type blowing filter bag, cleaning the dust attached to the filter bag, and then removing the dust through the dust collector's dust removal system. There are several filter bags inside the dust collector box in each horizontal layer of the box, and the box is divided into several layers. Each column of filter bags in the vertical direction controls the dust on the filter bag through a solenoid valve. There are as many solenoid valves as there are columns of filter bags inside the dust collector.

[0003] Usually, multiple solenoid valves of a dust collector are installed in a solenoid valve box to prevent dust from entering. Each solenoid valve is connected to a compressed air hose, which is then connected to a blowing device to intermittently clean the dust on the dust filter bag by controlling the switch of the solenoid valve.

[0004] During use, when the compressed air hose is damaged, or the vibration generated by the compressed air spray causes the compressed air hose to loosen, the maintenance personnel need to replace or reinstall the compressed air hose. Since the spacing between multiple solenoid valves inside the solenoid valve box is small, and the spacing between the solenoid valve and the back wall and bottom of the solenoid valve box is also small, it is inconvenient for maintenance personnel to remove and install the air pipe. In particular, when removing the compressed air hose from the solenoid valve, the maintenance personnel must press the solenoid valve air pipe joint position with their hands to pull out the compressed air hose. Due to the narrow space inside the solenoid valve box, the maintenance personnel's hands cannot reach the air pipe joint position at all, so the compressed air hose cannot be smoothly removed and reinstalled.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0026] Example:

[0027] Combined with Figure 1-4As shown, a disassembly and assembly tool for a compressed air hose in a solenoid valve box is used to disassemble and assemble the compressed air hose 3 connected to a plurality of solenoid valves 5 arranged in the solenoid valve box 4, and the solenoid valve 5 is connected to the compressed air hose 3 through a solenoid valve air pipe connector 6; the disassembly and assembly tool comprises: a clamping device and a pressing device, the clamping device 1 is used to clamp the compressed air hose to plug and unplug it from the solenoid valve air pipe connector to achieve the installation and removal of the compressed air hose; the pressing device 2 is used to squeeze the solenoid valve air pipe connector toward one end of the solenoid valve when removing the compressed air hose, so as to provide a reaction force with the clamping device, so as to facilitate the removal of the compressed air hose from the solenoid valve air pipe connector; by using the clamping device 1 and the pressing device 2 in combination, the compressed air hose in the solenoid valve box can be quickly disassembled and assembled, and it can prevent the solenoid valve air pipe connector and even the solenoid valve from being damaged by excessive pulling force when removing the compressed air hose.

[0028] In this embodiment, the solenoid valve air pipe joint is arranged below the solenoid valve, and is connected to the compressed air hose after being bent into the solenoid valve box. This connection method is more difficult to disassemble and assemble manually; of course, the disassembly and assembly tools of this embodiment can also be used for other compressed air hose connection methods.

[0029] Specifically, the clamping device 1 includes a pliers portion 11 and a clamping piece 12, wherein the pliers portion has a structure similar to that of existing pliers, has a V-shaped appearance, and has two parts, a handle and a pliers mouth. In this embodiment, no jaws are provided, but jaws may be provided for the purpose of having the functions of conventional pliers. Two clamping pieces 12 are vertically provided on the pliers mouth of the pliers portion, and the two clamping pieces 12 are pressed against each other by squeezing and closing the handle of the pliers portion, so that the arc-shaped grooves 121 arranged opposite to each other on the clamping pieces 12 are closed, so as to facilitate clamping of the compressed air hose.

[0030] Optionally, the clamping piece 12 is made of stainless steel, and when the two clamping pieces 12 are closed, the shape is rectangular. The two clamping pieces 12 are respectively welded to the jaws of the pliers, and when the clamping device 1 is in a closed state, the sides of the two clamping pieces are close together to form a rectangular piece with a circular hole in the middle.

[0031] Further preferably, the arc-shaped groove 121 is semicircular; when the sides of the two clamping pieces 12 are brought close together, the diameter of the middle circle is approximately smaller than the outer diameter of the compressed air hose, so that the compressed air hose and the clamping piece can be transitionally matched.

[0032] The clamping device 2 includes a sleeve 21, a connecting rod 22 and a clamping plate 23, wherein one end of the connecting rod 22 is coaxially connected to the sleeve 21, and the other end is vertically connected to the clamping plate 23. By adjusting the length of the connecting rod extending out of the sleeve, the overall length of the clamping device can be adjusted to adapt to the position of the solenoid valve air pipe joint in the solenoid valve box, and the clamping device can be easily stored through the retractable structure. A blind hole connecting the connecting rod is formed on the side of the lower end of the clamping plate 23, and an upward U-shaped groove 231 with a width less than the outer diameter of the solenoid valve air pipe connector is formed on the upper end. The width of the U-shaped groove is less than the outer diameter of the solenoid valve air pipe connector and larger than the outer diameter of the compressed air hose, so that the clamping plate structure on both sides of the U-shaped groove 231 can be abutted against the end of the solenoid valve air pipe connector, and the U-shaped groove 231 can avoid the compressed air hose to prevent the clamping device from contacting the solenoid valve air pipe connector and abutting against the compressed air hose at the same time, thereby hindering the removal of the compressed air hose; of course, this method is only applicable to the situation where the compressed air hose is inserted into the solenoid valve air pipe connector. When the compressed air hose is outerly arranged on the solenoid valve air pipe joint, the width of the U-shaped groove 231 of the clamping plate 23 can be set to be greater than or equal to the outer diameter of the solenoid valve air pipe joint, so that the U-shaped groove 231 can cooperate with the bending part of the solenoid valve air pipe joint to exert a reaction force on the solenoid valve air pipe joint to remove the compressed air hose, thereby facilitating the removal of the compressed air hose from the outside of the solenoid valve air pipe joint.

[0033] Optionally, the pressing sheet 23 is made of stainless steel, and the upper portion of the pressing sheet 23 has a U-shaped groove 231. The lower portion of the U-shaped groove 231 is semicircular, and the upper portion is rectangular, and the diameter of the semicircle is consistent with the width of the rectangle.

[0034] Preferably, the pressing piece 23 is welded to the head of the connecting rod 22; of course, the pressing device 2 can also be composed of only the connecting rod and the pressing piece.

[0035] When removing the compressed air hose from the solenoid valve, the utility model disassembly and assembly tool firstly presses the position of the air pipe joint of the solenoid valve with the pressing device, and then clamps the compressed air hose with the clamping device and pulls it out, so that the compressed air hose can be smoothly removed from the solenoid valve. When installing the compressed air hose, the clamping device clamps the compressed air hose and inserts it into the air pipe joint of the solenoid valve.

[0036] The disassembly and assembly tool of the utility model solves the problems that the installation spacing of multiple solenoid valves in the solenoid valve box is small, the space in the solenoid valve box is narrow, and it is inconvenient for maintenance personnel to disassemble and assemble the compressed air hose in the solenoid valve box by hand; it can operate in a smaller space in the solenoid valve box, avoiding the need for maintenance personnel to disassemble and assemble the entire solenoid valve box when manually disassembling and assembling, thus saving disassembly and assembly procedures and improving disassembly and assembly efficiency.

[0037] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
