Description

Safe explosion-proof clamp

Technical Field

The utility model relates to a pump truck connecting pipe protection technical field, in particular to safe explosion-proof clamp.

Background

The pump truck generally refers to a concrete pump truck, which is a machine for continuously conveying concrete along a pipeline by using pressure. Consists of a pump body and a connecting pipe 8. The structure is divided into a piston type, an extrusion type and a water pressure diaphragm type. The pump body is arranged on an automobile chassis, and then a telescopic or folding distributing rod is arranged to form the pump truck.

The concrete pump truck is formed by modifying a truck chassis, and is characterized in that a motion and power transmission device, a pumping and stirring device, a distributing device and other auxiliary devices are arranged on the chassis. The power of the concrete pump truck is transmitted to a hydraulic pump set or a rear axle through a power transfer case, and the hydraulic pump pushes a piston to drive a concrete pump to work. Then the concrete is conveyed to a certain height and distance by using a distributing rod and a connecting pipe 8 on the pump truck. When the connecting pipe 8 is subjected to a large conveying pressure, the connecting pipe is easy to burst, which not only causes production loss, but also threatens the life safety of workers.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model aims at providing a safe explosion-proof clamp with low costs, easy operation, effectual, can protect workman's safety, avoid economic loss.

In order to realize the above purpose, the utility model provides an including connecting rod post, cardboard, the cardboard divide into cardboard and lower cardboard, goes up the cardboard and is the clamp structure with lower cardboard, it is articulated with the one end of lower cardboard to go up the cardboard, goes up the cardboard and is provided with the connection journal stirrup with the other end of lower cardboard and fixes through bolt I, two it connects fixedly to be provided with two connecting rod posts that are the circumference equipartition at least between the cardboard.

In the scheme, the method comprises the following steps: the cardboard is square, two be provided with four connecting rod posts that are the circumference equipartition between the cardboard and connect fixedly, be favorable to increasing the effect of explosion-proof clamp, the connecting rod post that is the circumference equipartition surrounds the connecting pipe, makes safe explosion-proof clamp can both receive the effort of connecting pipe in all directions, can both play the blast proof effect in all directions.

In the scheme, the method comprises the following steps: the connecting support lug of the upper clamping plate and the lower clamping plate is provided with a rectangular notch, the connecting support lug is vertically welded on the rectangular notch and extends outwards, and the bolt I is arranged on the extending part of the connecting support lug. Go up the cardboard and the butt joint non-intersect of cardboard down, can't set up the bolt fastening, set up the connection journal stirrup, be convenient for pass through the bolt-up with last cardboard and lower cardboard and be in the same place. Set up the rectangle breach and provide the mounted position for connecting the journal stirrup, avoid connecting the tight hoop effect of cardboard and lower cardboard on the journal stirrup influence.

In the scheme, the method comprises the following steps: the thickness of the rest positions of the upper clamping plate and the lower clamping plate is the same except the hinged position of the upper clamping plate, a Y-shaped clamp is integrally arranged at the hinged position of the upper clamping plate, the lower clamping plate partially extends into the Y-shaped clamp, and a bolt II penetrates through the Y-shaped clamp to hinge the upper clamping plate and the lower clamping plate together. The hinge mode has simple structure and low cost, and more importantly, the Y-shaped clamp which is integrally arranged is not easy to damage and has long service life.

The utility model has the advantages that: the utility model discloses a set up two cardboard and press from both sides tightly on the pump truck connecting pipe, it is fixed with two splint connection to set up the connecting rod post again, can effectually prevent that the pump truck connecting pipe from bursting to protect workman's safety, avoid economic loss, moreover, the utility model discloses simple structure, easy and simple to handle, with low costs.

Detailed Description

The pump truck connecting pipe with the safety explosion-proof clamp shown in figures 1-3 mainly comprises a connecting pipe 8 and the safety explosion-proof clamp. The left end and the right end of the connecting pipe 8 are respectively provided with two circles of bulges which are spaced, and a circle of anti-slip groove 11 is formed between the two circles of bulges which are spaced. The antiskid groove 11 of the connecting pipe 8 is sleeved with a flange 9, a rubber ring 10 is arranged between the flange 9 and the antiskid groove 11, and the two connecting pipes 8 are fixedly connected together through the flange 9. The junction of two connecting pipes 8 is provided with safe explosion-proof clamp, and safe explosion-proof clamp uses ring flange 9 to set up as the intermediate point, and the even atress in both ends is difficult to the fracture about safe explosion-proof clamp, and the security is higher.

Safe explosion-proof clamp is by four connecting rod posts 5, two cardboard 3 are constituteed, cardboard 3 divide into cardboard 1 and lower cardboard 2, it is the clamp structure with lower cardboard 2 to go up cardboard 1, it is articulated with the one end of lower cardboard 2 to go up cardboard 1, except the articulated position of last cardboard 1, the thickness of going up cardboard 1 and the all the other positions of lower cardboard 2 is the same, it presss from both sides 6 to go up articulated position department an organic whole of cardboard 1 and be provided with the Y type, lower cardboard 2 local extension goes into in the Y type presss from both sides 6, bolt II passes the Y type and presss from both sides 6 and will go up cardboard 1 and lower cardboard 2 articulated together. The hinge mode has simple structure and low cost, and more importantly, the Y-shaped clamp which is integrally arranged is not easy to damage and has long service life. The other ends of the upper clamping plate 1 and the lower clamping plate 2 are provided with connecting lugs 4 and are fixed through bolts I. Go up cardboard 1 and lower cardboard 2 connect journal stirrup 4 department and be provided with rectangle breach 7, connect journal stirrup 4 vertical welding and outwards extend on rectangle breach 7, bolt I sets up the extension at connecting journal stirrup 4. Go up cardboard 1 and cardboard 2's butt joint non-intersect down, can't set up the bolt fastening, set up and connect journal stirrup 4, be convenient for with go up cardboard 1 and cardboard 2 down through the bolt-up together. Set up rectangle breach 7 and provide the mounted position for connecting journal stirrup 4, avoid connecting the tight hoop effect of cardboard 1 and lower cardboard 2 in the influence of journal stirrup 4. Cardboard 3 is square, is provided with four connecting rod posts 5 that are the circumference equipartition between two cardboards 3 and connects fixedly, is favorable to increasing the effect that the explosion-proof pressed from both sides, and connecting rod post 5 that is the circumference equipartition surrounds connecting pipe 8, makes the explosion-proof clamp of safety can both receive connecting pipe 8's effort in all directions, can both play the explosion-proof effect in all directions.
