According to the utility model, the damping layer is adhered on the outer circle of the pipe body of the spray head pipe, so that damping buffer contact is formed between the pipe body and the outer sleeve, when high-pressure water is sprayed, the friction force and viscous damping between the pipe body and the outer sleeve can counteract the instant reaction force generated when most high-pressure water is sprayed, so that a person can be effectively ensured to stably hold the spray pipe, and the person can freely and flexibly control the spray pipe, so that the water spraying is stable and uniform, the operation efficiency is greatly improved, and the quality of foundation pit operation is ensured.
Description
Technical Field
The utility model relates to a handheld spray head, in particular to a handheld spray head for foundation pit operation, and belongs to the technical field of building construction equipment.
Background
In foundation pit operation, a water spraying and soil discharging method is a common operation mode, and better operation effect can be achieved by adjusting the pressure of water spraying according to the difference of soil properties. When the existing handheld spray head for foundation pit operation sprays water, the instantaneous reaction force generated during high-pressure water flow spraying is large, so that the spray pipe and the joint are easy to fall off, and meanwhile, the hand of a person holding the spray pipe is extremely easy to operate the spray pipe due to the instantaneous reaction force, so that the water spraying is unstable, and the foundation pit operation is influenced.
Disclosure of Invention
The utility model aims to provide a handheld spray head for foundation pit operation, which is simple and reliable in structure and convenient for personnel to operate and control.
The utility model is realized by the following technical scheme:
a handheld nozzle for foundation pit operation comprises a high-pressure pump, a hollow joint, a nozzle pipe and an outer sleeve; the shower nozzle pipe includes body and high-pressure shower nozzle, the both ends that hollow connects connect soon with high-pressure pump joint and body inner end respectively, and outer tube slip cap dress is on the body excircle, high-pressure shower nozzle closes soon on the outer end of body, and high-pressure shower nozzle's external diameter is greater than the external diameter of body, forms spacing step at the outer end of body.
The object of the present utility model can be further achieved by the following technical means.
In the handheld nozzle for foundation pit operation, the damping layer is adhered to the outer circle of the pipe body.
The handheld spray head for foundation pit operation is characterized in that a lifting handle is arranged on the upper side of the high-pressure pump.
The handheld spray head for foundation pit operation is characterized in that a handle is arranged on the lower side of the high-pressure pump.
The utility model has simple and compact structure and low cost, and the connection between the nozzle pipe and the hollow joint is stable and reliable and is not easy to fall off. According to the utility model, the damping layer is adhered on the outer circle of the pipe body of the spray head pipe, so that damping buffer contact is formed between the pipe body and the outer sleeve, when high-pressure water is sprayed, the friction acting force and viscous damping between the pipe body and the outer sleeve can counteract the instant reaction force generated when most high-pressure water is sprayed, so that a person can be effectively ensured to stably hold the spray pipe, and the person can freely and flexibly control the spray pipe, so that the water spraying is stable and uniform, the operation efficiency is greatly improved, and the quality of foundation pit operation is ensured. The lifting handle and the handle on the high-pressure pump can be conveniently taken by personnel to carry and hold the utility model.
Advantages and features of the utility model will be illustrated and explained by the following non-limiting description of preferred embodiments, given by way of example only with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic perspective view of the present utility model.
Detailed Description
The utility model is further described below with reference to the drawings and examples.
As shown in fig. 1, the present utility model includes a high-pressure pump 1, a hollow joint 2, a head pipe 3, and an outer sleeve 4. The upper side of the high-pressure pump 1 is provided with a handle 11, and the lower side thereof is provided with a handle 12. The shower nozzle pipe 3 includes body 31 and high pressure shower nozzle 32, and the both ends that hollow joint 2 was connected with the joint of high pressure pump 1 and the inner spin of body 31 respectively, and the outer circle of body 31 is last to be adhered with damping layer 33, and outer tube 4 slip-on suit is on damping layer 33, can make things convenient for personnel to hold shower nozzle pipe 3. Because the damping layer 33 has certain elasticity, damping buffer contact is formed between the outer sleeve 4 and the pipe body 31, when the outer sleeve and the pipe body are relatively displaced, friction force exists between the outer sleeve and the pipe body, viscous damping exists between the outer sleeve and the pipe body, and a large friction buffer effect is achieved. The high-pressure nozzle 32 is screwed on the outer end of the pipe body 31, the outer diameter of the high-pressure nozzle 32 is larger than the outer diameter of the pipe body 31, and a limit step 34 is formed on the outer end of the pipe body 31, so that the outer sleeve 4 can be prevented from falling off.
When the water spray is used for discharging soil, a constructor holds the handle 12 by one hand and holds the outer sleeve 4 by the other hand, and opens the working switch of the high-pressure pump 1, at this time, high-pressure water flow is sprayed out from the high-pressure spray nozzle 32, the reaction force generated by the high-pressure water flow enables the spray nozzle pipe 3 to move backwards, the outer sleeve 4 and the spray nozzle pipe 3 generate relative displacement, at this time, under the action of friction force and viscous damping between the outer sleeve 4 and the damping layer 33, the relative displacement between the outer sleeve 4 and the spray nozzle pipe 3 is slow, the high-pressure spray nozzle 32 sprays high-pressure water flow more stably, and the worker can easily control the spray nozzle pipe 3. The pressure of the high-pressure water flow sprayed by the spray head pipe 3 can be adjusted by adjusting the high-pressure pump 1, so that the water spraying and soil discharging operation can be smoothly completed.
In addition to the above embodiments, other embodiments of the present utility model are possible, and all technical solutions formed by equivalent substitution or equivalent transformation are within the scope of the present utility model.
