Description

Technical Field

[0001] The utility model belongs to the technical field of air tightness detection of fire extinguishers, and specifically relates to a vertical water testing machine. Background Art

[0002] During the production and testing process, fire extinguishers must undergo a water test procedure, that is, after filling, they are placed in a water tank to observe whether the fire extinguisher is leaking, and then taken out after the test. Regardless of whether it is placed in or taken out of the water tank, the transfer equipment usually used is a clamping cylinder to achieve the transfer. The clamping cylinder can only clamp one fire extinguisher and cannot be expanded, which makes the transfer efficiency of the fire extinguisher relatively low. In addition, the underwater inspection and transportation are generally horizontal transportation, which occupies a large space, resulting in a small number of fire extinguishers transported. Utility Model Content

[0003] In view of the above-mentioned deficiencies described in the prior art, the utility model provides a vertical water testing machine.

[0004] The technical solution adopted by the utility model is:

[0005] A vertical water testing machine includes a water tank, a vertical conveying mechanism and a lifting clamping transfer mechanism. The vertical conveying mechanism is arranged at the bottom of the water tank, and the lifting clamping transfer mechanism is installed at both ends of the water tank. The lifting clamping transfer mechanism is located above the vertical conveying mechanism. The vertical conveying mechanism includes a conveying support bottom plate, and conveying structures are arranged on both sides of the conveying support bottom plate. A plurality of limit structures are arranged between the conveying parts of the two conveying structures, and the setting direction of the limit structures is perpendicular to the conveying direction of the conveying structures; the adjacent limit structures and the conveying support bottom plates form a vertical pushing station; the clamping claw structure of the lifting clamping transfer mechanism transfers the items at the vertical pushing station. The fire extinguisher is transferred or transferred out to the vertical conveying mechanism through the lifting clamping transfer mechanism, and the limit structure pushes the vertically placed bottle forward with the movement of the conveying structure, so that more fire extinguishers can be detected and conveyed at one time, and the detection efficiency is improved. The lifting clamping transfer mechanism is used to improve the efficiency of transfer in and out.

[0006] As a preferred solution of the utility model, the limiting structure includes a limiting connecting plate and a limiting rod, and a limiting connecting plate is installed at both ends of the limiting rod.

The limiting structure is placed horizontally between the two conveying chains, and fire extinguishers can be placed between two adjacent conveying chains. Because it is placed vertically, multiple fire extinguishers can be placed in the same vertical pushing station. There are multiple vertical pushing stations, so the number of fire extinguisher detections increases. And it is installed on the conveying chain through a limiting connecting plate, so that the position of the limiting structure and the number of installations can be adjusted as needed, and the setting height of the limiting rod should be above the middle of the fire extinguisher, so that the fire extinguisher will not fall when the forward moving force is applied, and the entire conveying chain is continuously and slowly running.

[0008] As a preferred solution of the utility model, the lifting clamping transfer mechanism includes a lifting structure, an opening and closing clamping mechanism, a horizontal moving structure, a transfer and conveying structure and a lifting frame; the lifting frame is installed at the upper opening of the water tank; the lifting base plate of the lifting structure is slidably installed on the lifting frame, the horizontal moving structure is fixed on the lifting frame, the moving part of the horizontal moving structure is connected to the lifting base plate, and the lifting part of the lifting structure is connected to the opening and closing clamping mechanism; the transfer and conveying structure is installed on the side of the opening and closing clamping mechanism, and the rotating conveying structure is installed on the water tank. The lifting frame is used as an integral support frame, and a linear guide rail is installed on the top of the lifting frame. The lifting base plate is connected to the slider of the linear guide rail, and the moving part of the horizontal moving structure is connected to the lifting base plate and drives the lifting base plate to move back and forth along the linear guide rail, thereby driving the entire device to approach and move away from the transfer and conveying structure. The lifting structure drives the opening and closing clamping mechanism to approach and move away from the vertical conveying mechanism and the transfer and conveying structure in the vertical direction. When the opening and closing clamping mechanism is discharging and taking materials, the horizontal moving structure and the conveying chain are synchronously operated to complete the material taking and discharging.

[0009] As a preferred solution of the utility model, the opening and closing clamping mechanism includes an opening and closing mounting base plate, a clamping claw structure and an opening and closing power structure. The opening and closing mounting base plate is connected to the lifting part of the lifting structure, and at least one clamping claw structure is installed on the lower end surface of the opening and closing mounting base plate, each clamping claw structure includes a clamping claw I and a clamping claw II, and the clamping claw I and the clamping claw II are both slidably installed on the lower end surface of the opening and closing mounting base plate; the upper end surface of the opening and closing mounting base plate is provided with an opening and closing power structure, and the opening and closing power structure includes an opening and closing movable base plate, an opening and closing movable power part and a clamping claw opening and closing connecting column group, the opening and closing movable base plate is installed on the opening and closing mounting base plate and can move relative to the opening and closing mounting base plate under the action of the opening and closing movable power part; the opening and closing movable base plate The moving direction is perpendicular to the sliding direction of the clamping jaw structure; at least one opening and closing slide groove group is provided on the opening and closing moving base plate, and each opening and closing slide groove group includes an opening and closing slide groove I and an opening and closing slide groove II; the inclination directions of the opening and closing slide groove I and the opening and closing slide groove II are opposite; the opening and closing slide groove group corresponds to the clamping jaw opening and closing connecting column group one by one, and each clamping jaw opening and closing connecting column group includes a clamping jaw opening and closing connecting column I and a clamping jaw opening and closing connecting column II; the clamping jaw opening and closing connecting column I is installed in the opening and closing slide groove I and the clamping jaw opening and closing connecting column I is connected to the clamping jaw I after passing downward through the clearance hole of the opening and closing installation base plate; the clamping jaw opening and closing connecting column II is installed in the opening and closing slide groove II and the clamping jaw opening and closing connecting column II is connected to the clamping jaw II after passing downward through the clearance hole of the opening and closing installation base plate. The opening and closing moving power part is fixed on the opening and closing mounting base plate and realized by using a telescopic cylinder. The piston rod of the telescopic cylinder is connected to the opening and closing moving base plate through a connecting column and drives the opening and closing moving base plate to reciprocate along the opening and closing linear guide rail. Because the opening and closing slide groove I and the opening and closing slide groove II are distributed in an eight-shaped shape, the jaw opening and closing connecting column I and the jaw opening and closing connecting column II are fixed on the corresponding jaws at one end, so they will drive the corresponding jaws I and jaws II to move closer or farther away. However, due to the existence of the linear guide rail I, the jaws I and jaws II move linearly along the linear guide rail I, that is, the forward and backward movement of the opening and closing moving base plate is converted into the left and right movement of the jaws I and jaws II.

[0010] As a preferred solution of the utility model, linear guide rails I are symmetrically arranged on both sides of the clearance hole on the lower end surface of the opening and closing installation base plate, and the clamping jaws I and II are connected to the corresponding sliders of the two linear guide rails I at the same time.

[0011] As a preferred solution of the utility model, an opening and closing sliding bracket is arranged between the opening and closing slide groove I and the opening and closing slide groove II on the opening and closing mounting base plate, an opening and closing linear guide rail is arranged on the opening and closing sliding bracket, and a slider of the opening and closing linear guide rail is connected to the opening and closing movable base plate; the setting direction of the opening and closing linear guide rail is perpendicular to the setting direction of the linear guide rail I. The inclined opening and closing slide groove, the opening and closing linear guide rail and the linear guide rail I cooperate with each other to realize the mutual approach or distance between the clamping jaws I and the clamping jaws II, thereby realizing the clamping and release of the fire extinguisher.

[0012] As a preferred solution of the utility model, the lifting structure includes a lifting base plate, a lifting track plate, a rack, a gear and a lifting motor. The lower part of the lifting track plate is mounted on the opening and closing mounting base plate. The lifting base plate is mounted on the top of the lifting track plate. The rack is passed through the lifting base plate and then on the lifting track plate. The rack is meshed with the gear. The gear is mounted on the output shaft of the lifting motor, and the lifting motor is fixed on the lifting base plate. The lifting motor drives the gear to rotate. Since the lifting base plate does not move up and down, the rack meshed with the gear will move up and down with the lifting track plate. The opening and closing clamping mechanism connected to the bottom of the lifting track plate moves up and down together, changing the vertical position.

[0013] As a preferred solution of the utility model, a linear guide rail is arranged on the outer side of the lifting track plate, and a slider of the linear guide rail is connected to the lifting base plate.

[0014] The utility model uses a lifting clamping transfer mechanism to achieve the transfer of the fire extinguisher when it enters and exits the water, and the lifting clamping transfer mechanism changes the clamping of the fire extinguisher to use an opening and closing movable base plate provided with an eight-shaped opening and closing slide structure for driving. The opening and closing movable base plate can achieve the effect of driving multiple clamps to open and close at one time, thereby improving the efficiency of the fire extinguisher transfer. The opening and closing movable power part is connected to the opening and closing movable base plate through a connecting column and drives the opening and closing movable base plate to reciprocate along the opening and closing linear guide rail. Because the opening and closing slide grooves I and II are distributed in an eight-shaped shape, the clamping jaw opening and closing connecting column I and the clamping jaw opening and closing connecting column II are fixed on the corresponding clamping jaws at one end, so they will drive the corresponding clamping jaws I and II to move closer or farther away. However, due to the existence of the linear guide rail I, the clamping jaws I and II move linearly along the linear guide rail I. The water tank is transported vertically, and the limit rods set between the conveying chains and the fixed supporting bottom plate are used to form a fire extinguisher pushing station. There are multiple pushing stations on the supporting bottom plate. The fire extinguishers are placed vertically. Each pushing station can accommodate multiple fire extinguishers. More fire extinguishers can be placed on the entire supporting bottom plate, which improves the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

And the limit connecting plate is installed on the conveyor chain, so that the position of the limit structure and the number of installations can be adjusted as needed, and the setting height of the limit rod should be above the middle of the fire extinguisher, so that the fire extinguisher will not fall over when the forward force is applied.

Linear guide rails are arranged on the outer side of the lifting track plate 312, and the slider of the linear guide rail is connected to the lifting base plate.

[0032] The lifting motor drives the gear to rotate. Because the lifting base plate does not move up and down, the rack meshing with the gear will move up and down with the lifting track plate.
