Description
Technical field
The utility model belongs to construction apparatus technical field, particularly a kind of concrete pump pipe shock damping device.
Background technique
Concrete pump is the indispensable a kind of engineering construction machinery of modern architecture industry, and it has and increases substantially work efficiency, reduces labor strength, accelerating construction progress, saves the plurality of advantages such as labour cost.Concrete pumping technique relies on its efficient concrete conveyance rate, and be widely used in tall building concrete construction, concrete mixer is connected by concrete pump pipe with the material distributing machine of work surface.When concrete is carried by pump line, because concrete has huge active pressure, concrete pump pipe is made to produce huge vibrations (or mobile).
Concrete is in pipeline transport process, and it is many-sided that concrete pump pipe shakes the harm brought, and one is can form huge impact load to floor, causes floor to injure, affects construction quality; Two is cause damage to concrete pump pipe joint, shortens its working life; Three is one of factors causing pump line to block, and in concreting process, pump line shake is severe, and drive horizontal pipe to rock, horizontal pipe inner concrete aggregate sinks, and causes plugging.Therefore, to be fixed concrete pump pipe in tall building concrete construction.
Traditional concrete pump pipe means of fixation utilizes flitch and timber wedge to be stuck in floor slab preformed hole by concrete pump pipe, but due to the vibrations repeatedly of concrete pump pipe, flitch and timber wedge easily loosen, thus easily cause solid failure.Patent CN202187562U provides a kind of concrete pump pipe fixing device, and comprise two pieces of base plates mutually spliced, base plate stitching portion offers arc port, base plate is vertically provided with the arc plate adapted with arc port, and base plate side edge is provided with fixed hole.This patent solves the deficiency of conventional concrete pump line means of fixation, but the installation of device is comparatively complicated, effectively can not eliminate the enormous impact load that concrete pump pipe vibrations are formed floor.
Model utility content
The purpose of this utility model is the above-mentioned technical problem overcoming concrete pump pipe vibrations initiation, provides a kind of concrete pump pipe and moves damping device.This device is taken and is torn open conveniently, and cooperation, effectively can eliminate the vibrations of concrete pump pipe.
To achieve these goals, the technological scheme that the utility model is taked is:
A kind of concrete pump pipe shock damping device, resilient rubbber cushion, flitch, elastic block rubber and susceptor plate is symmetrical arranged at pump line outer side wall, susceptor plate is fixed on the floor that pump line passes by EXPANSION ANCHOR BOLTS, susceptor plate is a spill frame structure, elastic block rubber is filled in the base portion of susceptor plate, one end of flitch to be inserted in susceptor plate and is fitted with elastic block rubber, the other end of flitch stretches out susceptor plate and for supporting resilient rubbber cushion, resilient rubbber cushion is close to pump line outer side wall.
Preferred as described concrete pump pipe shock damping device, the side that described resilient rubbber cushion and pump line outer side wall fit, has the arcuate structure adapted with pump line outer side wall.
Compared with existing concrete pump line fixing device, the beneficial effects of the utility model are mainly reflected in:
The concrete pump pipe shock damping device that the utility model provides, be made up of two groups of resilient rubbber cushions, flitch, elastic block rubber and susceptor plates, susceptor plate is fixedly connected with floor by EXPANSION ANCHOR BOLTS, elastic block rubber is filled in the base portion of susceptor plate, flitch prevents and treats its slippage for supporting resilient rubbber cushion, and resilient rubbber cushion and pump line outer side wall fit tightly.Whole apparatus structure is simple, without the need to the fixation of the complexity such as welding, after construction completes, is also convenient to remove this damping device.
This damping device mainly relies on by the elasticity of the resilient rubbber cushion compressed, and reduces the vibration amplitude of pump line, and in the vibrations process of pump line, provide a reverse power to offset the vibration amplitude of a part of pump line.Elasticity because of resilient rubbber cushion is linear change, therefore the buffering of amplitude in certain limit can be realized, the plugging risk that the concrete aggregate that the vibrations reducing pump line with this bring sinks to producing, alleviate and concrete pump pipe joint is caused damage, and this device is because make pump line and floor non-direct contact, greatly can also reduce because of the continuous generation impacting the cracks on floor slab that floor causes of pump line vibrations, thus promote the quality of building structure product.

Description of reference numerals: 1, resilient rubbber cushion; 2, flitch; 3, elastic block rubber; 4, susceptor plate; 5, EXPANSION ANCHOR BOLTS; 6, pump line; 7, floor.
Embodiment
For the ease of understanding the purpose of this utility model, technological scheme and effect thereof, now will be elaborated further the utility model in conjunction with the embodiments.
In the construction of tall building, what first will solve is exactly concrete supply problem.Due to building height superelevation yet to be built, general concrete pump pipe technique for fixing can not meet the requirement now to architecture quality, what therefore want high-quality completes construction, solves pump line vibrations in concrete delivery service to the injury of floor and pump pipe union and cause the problem of plugging just to become particularly important.
This gives a kind of concrete pump pipe shock damping device, as shown in Figure 1, be symmetrical arranged resilient rubbber cushion 1, flitch 2, elastic block rubber 3 and susceptor plate 4 at pump line outer side wall.Resilient rubbber cushion 1 fits tightly at pump line outer side wall.Preferred as embodiment, the side that resilient rubbber cushion 1 and pump line outer side wall fit, has the arcuate structure adapted with pump line outer side wall, and can increase the area of contact of resilient rubbber cushion 1 and pump line like this, dispersion pump line is to the active force of resilient rubbber cushion 1; Meanwhile, also increase resilient rubbber cushion 1 and the frictional force of pump line, prevent the slippage of resilient rubbber cushion 1.
Susceptor plate 4 is fixed on the floor that pump line passes by EXPANSION ANCHOR BOLTS 5, and especially, susceptor plate 4 is a spill frame structure, and elastic block rubber 3 is filled in the base portion of spill susceptor plate 4.Flitch 2 for supporting resilient rubbber cushion 1, and transmits the active force of pump line to resilient rubbber cushion 1.One end of flitch 2 is inserted in susceptor plate 4, and fits with elastic block rubber 3, the other end of flitch stretch out susceptor plate 4 and with elastic block rubber 3 close contact.
Described in the present embodiment, the working principle of concrete pump pipe shock damping device is, rely on by the resilient rubbber cushion 1 that directly compresses and by the elasticity of elastic block rubber 3 indirectly compressed, reduce the vibration amplitude of pump line, and in the vibrations process of pump line, provide a reverse power to offset the vibration amplitude of pump line.Therefore, the principle that whole device eliminates concrete pump pipe vibrations is simple and practical, and project organization is simple, is convenient to dismounting.
The utility model is done above in conjunction with the embodiments and further described, but the utility model is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.Such as, resilient rubbber cushion 1 can be the integral structure component that middle part offers arc port, is sleeved on pump line; Flitch 2 also can select the square structure body of stainless steel or rigid plastics material, also can realize the non-square structure of same effect; Elastic block rubber 3 also can be the spring of metal material or the elastic component of non-metallic material.
