Description

A kind of concrete pump and concrete piston for concrete pump

Technical field

The utility model relates to technical field of engineering machinery, relates in particular to a kind of concrete pump and concrete piston for concrete pump.

Background technique

Concrete piston for concrete pump moves reciprocatingly in concrete conveying cylinder, and operating rate is high, bears pressure large, directly contacts with concrete, and is easy to wear, perishable.Usually make the piston matrix with steel, make the concrete seal with polyurethane or abrasive rubber.Concrete seal lip limit pressurized carries cylinder to contact in the also reciprocating process with concrete, and the concrete seal is easy to wear, in case the concrete seal is impaired, pumping procedure can lose pumping pressure, causes the concrete pump suction poor, and discharging is slow, can damage simultaneously concrete and carry cylinder.When generally dirt appears in water in finding tank, need in time to change to improve the pumping efficiency of complete machine.

At present, concrete piston integral body need to be carried to entirely when changing the concrete piston with the concrete seal, step up piston, assembling-disassembling bolt is changed the concrete seal.General common method has support oil cylinder to step up the dismounting method when changing the concrete piston with the concrete seal: concrete piston integral body is carried to entirely, utilizes support oil cylinder to step up the concrete piston, assembling-disassembling bolt needs many people to cooperate and carries out disassemble and assemble work.Bench vice steps up the dismounting method: the place that adds clamping tool is being arranged, as utilizing bench vice to step up piston head and carry out disassemble and assemble work.Because nothing effectively adds clamping tool, disassembly process wastes time and energy.

Summary of the invention

In view of this, a technical problem to be solved in the utility model provides a kind of concrete pump, fixing concrete piston when dismounting concrete piston.

A kind of concrete pump comprises concrete piston 1, and the end face of described concrete piston 1 arranges limiting stopper 2; Described limiting stopper 2 cooperates with positioning hole 4 on being arranged on the concrete pump housing 3, limits described concrete piston rotation.

According to an embodiment of concrete pump of the present utility model, further, described limiting stopper 2 is cuboid or hexahedron.

According to an embodiment of concrete pump of the present utility model, further, the outer installment concrete seal of described concrete piston, the material of described concrete seal is polyurethane or abrasive rubber.

Concrete pump of the present utility model and concrete piston for concrete pump, fixing concrete piston when dismounting concrete piston is increased work efficiency and the hommization degree.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do one to the accompanying drawing of required use in embodiment or the description of the Prior Art and introduce simply, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the schematic diagram according to an embodiment of concrete pump of the present utility model.

Embodiment

With reference to the accompanying drawings the utility model is described more fully, exemplary embodiment of the present utility model wherein is described.Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with figure and embodiment the technical solution of the utility model is carried out many-sided description.

Fig. 1 is the schematic diagram according to an embodiment of concrete pump of the present utility model.Concrete pump is a kind of with the engineering machinery of concrete conveyance to specified position, comprises concrete pump, Vehicular concrete pump, towed concrete pump.The concrete piston is a kind of pump concrete Sealing, comprises the concrete seal and supports concrete seal matrix.At present, how therefore spacing problem when dismounting piston head Main Problems is the piston head dismounting in the industry, realize that the light dismounting piston head of a people is the emphasis that the technical program is considered.

As shown in the figure, concrete pump comprises concrete piston 1, and concrete pump housing 3(Fig. 1 has only drawn the part of the concrete pump housing).The end face of concrete piston 1 arranges limiting stopper 2.Limiting stopper 2 cooperates with positioning hole 4 on being arranged on the concrete pump housing 3, the rotation of restriction concrete piston.According to an embodiment, can adopt the devices such as buckle, hook, the rotation of restriction concrete piston.For example, at the end face of concrete piston 1 hook is set, at the pump housing 3 shackle is set.

According to an embodiment of the present utility model, limit stoper is cuboid or hexahedron, perhaps is other shape.For example, limiting stopper 2 can be double-screw bolt, and positioning hole 4 is tapped hole, and limiting stopper 2 can be threaded with positioning hole 4.The outer installment concrete seal of concrete piston, the material of concrete seal is polyurethane or abrasive rubber.

According to an embodiment of the present utility model, a kind of concrete piston for concrete pump is provided, its end face arranges limit stoper.Limit stoper is cuboid or hexahedron.The outer installment concrete seal of concrete piston, the material of concrete seal is polyurethane or abrasive rubber.

The utility model adopts the structure that increases outstanding limiting stopper at the first end face of piston, and the while arranges the positioning hole of respective shapes in the proper site of other parts of the concrete pump housing or concrete pump.When assembling-disassembling bolt, the limiting stopper that piston is outstanding and the positioning hole of respective shapes are used in conjunction with, and to reach spacing fixed piston, realize the work of the light dismounting piston head of a people.

During the dismounting piston, piston need not be moved away from complete machine, can realize the dismounting piston on complete machine, has improved the dismounting piston efficiency.In industry being at first to arrange, also is a kind of embodiment of central pump humanization designing.When tearing piston open, the limiting stopper that piston is outstanding cooperates with the positioning hole on the complete machine, fixes the purpose of demounting bolt to realize piston.During the assembling piston, equally that piston is outstanding limiting stopper cooperates with the positioning hole on the complete machine, other structural members of assembling piston.When tighting a bolt, because piston is fixed, can realize that bolt effectively tightens, the process of whole dismounting concrete seal is time saving and energy saving.

Description of the present utility model provides for example with for the purpose of describing, and is not exhaustively or with the utility model to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiments with various modifications that the utility model design is suitable for special-purpose.
