Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting devices, in particular to a diaphragm pump valve cone hoisting device. Background Art

[0002] Diaphragm pumps, also known as control pumps, are the main type of actuators. They receive control signals from the control unit and use power to change the fluid flow rate. Diaphragm pumps are indispensable for regulating and controlling a certain parameter (such as temperature, pressure, flow, liquid level, etc.) in the process.

[0003] With the rapid development of modern industry, diaphragm pumps are used in more and more fields. As a consumable part, the valve cone of the diaphragm pump needs to be replaced frequently. During the replacement process, the valve cone of the diaphragm pump is usually disassembled by manual lifting. A steel bar is inserted into the middle of the bolt hole of the valve cone, and the staff lifts the valve cone upward through the steel bar. In this way, on the one hand, the valve cone itself is heavy and the staff is easy to get injured. On the other hand, the valve cone is easy to fall off, causing the valve cone to be damaged by collision. Therefore, the replacement of the valve cone of the diaphragm pump is difficult and there are also safety hazards. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a diaphragm pump valve cone lifting device, which connects the sleeve and the valve cone together through a locking pin, and then uses a crane to hook the lifting ring to lift the valve cone, thereby realizing stable disassembly of the valve cone, which not only improves the damage of the valve cone due to collision, but also reduces safety hazards.

[0005] The utility model provides a diaphragm pump valve cone hoisting device, which is used for the hoisting work of the valve cone. The valve cone is penetrated with a bolt hole and comprises a sleeve. The sleeve is sleeved on the valve cone. Two through holes are formed on the circumferential side wall of the sleeve. The through holes and the bolt holes are arranged opposite to each other. A hoisting ring is arranged on the top of the sleeve. Locking pins are inserted in the through holes and the bolt holes.

[0006] Furthermore, at least three sets of tightening assemblies are arranged in the sleeve, and the tightening assemblies are arranged around the sleeve. The tightening assemblies include a tightening screw, which is threadedly connected in the sleeve and horizontally penetrates the sleeve. A rotating rod is arranged at one end of the tightening screw, and the other end of the tightening screw is pressed against the valve cone.

[0007] Furthermore, an arc-shaped tightening piece is arranged at one end of the tightening screw rod close to the valve cone, the tightening piece and the tightening screw rod are rotationally connected via a hinge ball, and the tightening piece abuts against the valve cone.

[0008] Furthermore, an accommodating groove is provided on the inner circumferential side wall of the sleeve, and the tightening piece is movably arranged in the accommodating groove.

[0009] Furthermore, at least one limiting rod is provided on the side of the tightening piece away from the valve cone, the limiting rod is slidably connected in the sleeve, and the limiting rod horizontally penetrates the sleeve.

[0010] Furthermore, an anti-dropout component is provided in the locking pin, and the anti-dropout component includes a push rod slidably inserted into the locking pin, the push rod is arranged along the length direction of the locking pin, one end of the push rod passes through the locking pin, a compression spring is arranged between the other end of the push rod and the locking pin, a movable groove is provided in the locking pin, the movable groove is located at one end close to the compression spring, an anti-dropout ball is movably provided in the movable groove, the anti-dropout ball part is located on the outside of the locking pin, and a yield groove for moving the anti-dropout ball inward is provided in the push rod.

[0011] Furthermore, a limit block is arranged on the push rod, a limit slot is arranged in the lock pin, and the limit block is slidably arranged in the limit slot.

[0012] Furthermore, a connecting chain is arranged on the sleeve, and one end of the connecting chain away from the sleeve is arranged on the locking pin.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Before removing the valve cone, first put the sleeve on the valve cone, then rotate the sleeve to align the through hole with the bolt hole, insert the lock pin into the through hole and the bolt hole, use a crane to hook the lifting ring and lift it upward to lift the valve cone, thereby completing the removal of the valve cone. Using a lifting device to remove the valve cone not only improves the risk of collision and damage to the valve cone, but also reduces safety hazards.

[0015] (2) Since valve cones come in different sizes, when the valve cone is smaller than the inner diameter of the sleeve, after the sleeve is put on the valve cone, the rotating rod is rotated, and the rotating rod drives the tightening screw to rotate. The tightening screw pushes the tightening plate to move, and the tightening plate presses against the valve cone, thereby preventing the valve cone from shaking in the sleeve and improving the lifting stability.

[0016] (3) Before inserting the locking pin, push the push rod first to move the anti-drop ball inward and fall into the clearance groove, and then insert the locking pin into the bolt hole. When the anti-drop ball passes through the bolt hole, release the push rod, and the compression spring pushes the push rod to move. The push rod lifts the anti-drop ball so that the anti-drop ball is partially located outside the locking pin. Due to the protrusion of the anti-drop ball, the locking pin cannot be pulled out of the bolt hole at this time, thereby realizing the anti-drop effect of the locking pin and improving the safety of lifting.

The connecting chain 5 is used to connect the sleeve 2 and the locking pin 4 to prevent the locking pin 4 from being lost.

[0026] At least three groups of tightening assemblies 6 are arranged in the sleeve 2. In this embodiment, the tightening assemblies 6 are preferably three groups. The three groups of tightening assemblies 6 are evenly arranged horizontally around the sleeve 2. The tightening assembly 6 includes a tightening screw 60, which is threadedly connected to the sleeve 2. The tightening screw 60 horizontally penetrates the circumferential side wall of the sleeve 2. One end of the tightening screw 60 located outside the sleeve 2 is vertically fixedly connected with a rotating rod 61. One end of the tightening screw 60 located inside the sleeve 2 is provided with a tightening sheet 62. The tightening sheet 62 is arranged in an arc shape and abuts against the valve cone 1. The tightening sheet 62 is used to increase the contact area between the tightening screw 60 and the valve cone 1.

[0027] A hinge ball 63 is fixedly connected to one end of the tightening screw 60 close to the tightening plate 62, and the hinge ball 63 is rotatably connected to the tightening plate 62, so that the tightening screw 60 and the tightening plate 62 can rotate relative to each other; two limit rods 64 are fixedly connected to the side of the tightening plate 62 away from the valve cone 1, and the two limit rods 64 are located on the upper and lower sides of the tightening screw 60. The limit rods 64 horizontally penetrate the circumferential side wall of the sleeve 2 and are slidably penetrated in the sleeve 2. The limit rods 64 are used to limit the rotation of the tightening plate 62; a receiving groove 65 is opened on the inner circumferential side wall of the sleeve 2, and the tightening plate 62 is movably arranged in the receiving groove 65.

[0028] An anti-slip assembly 7 is provided in the lock pin 4, and the anti-slip assembly 7 includes a push rod 70 arranged along the length direction of the lock pin 4, a slide groove 71 is opened in the lock pin 4 along its own length direction, the push rod 70 is slidably inserted into the slide groove 71, one end of the push rod 70 passes through the lock pin 4, and a compression spring 72 is provided between the other end of the push rod 70 and the bottom of the slide groove 71, and the compression spring 72 has a tendency to drive the push rod 70 to move in the direction of sliding out of the lock pin 4; a movable groove 73 is opened in the lock pin 4, the movable groove 73 is located at one end of the lock pin 4 close to the compression spring 72, and an anti-slip ball 74 is movably arranged in the movable groove 73, and the anti-slip ball 74 is partially located on the outside of the lock pin 4 and can be clamped on the valve cone 1, thereby preventing the lock pin 4 from sliding out of the bolt hole 10; the outer side of the movable groove 73 is in a closed shape and is smaller than the diameter of the anti-slip ball, thereby preventing the anti-slip ball 74 from sliding out of the movable groove 73.
