Description
Technical field
The utility model relates to construction equipment field, specially a kind of concrete bush hammer.
Background technique
In highway, bridge and the medium concrete topping work progress of municipal works, in order to make applying for two construction stages
Work face is firmly bonded, and generally requires to carry out dabbing processing to concrete surface, i.e., it is recessed to dig out a rule in concrete structural surface
Then trace is rinsed with water completely, mainly improves the adhesive force of concrete surface, the cohesive force of pouring concrete and it after increase.
Traditional dabbing method, be manually with sharp hammer tool concrete surface percussion carry out piston strike, but
It is dabbing heavy workload and inefficiency in this way.
In the prior art, the utility model patent of Patent No. CN201620638706.5 discloses a kind of hand-held pneumatic
Dabbing machine, including burr body mounting plate, hand cradle, handle, piston rod, dabbing head and compressed air source；In this scenario, pass through pressure
Contracting air-source compressed air enters the air cavity in piston rod from air inlet, and compressed air pushes piston rod to impact downwards rapidly, band
Dynamic dabbing head strikes concrete surface；Then compressed air is discharged by the gas vent on piston rod, and compressed air continues through work
Air inlet on plug sleeve enters the gap between piston bush and piston rod, and the ladder-like backhaul point on piston rod is pushed to make piston rod
It moves up, works repeatedly, realize the continuous strike of dabbing head concrete surface.
Solve heavy workload, low efficiency brought by manual work, and the ropy problem of dabbing in the program, still
The structure design used in the program, the main by weight that will lead to hand-held dabbing machine concentrates on the side of hand cradle, in user
When holding hand cradle replacement dabbing region, enables the hand of user always in the unilateral weight for bearing dabbing machine, be easy to cause hand
Fatigue；And when dabbing head and concrete surface are hit, dabbing chance generates very big vibration under reaction force, also to user
Hand generate very big burden.
Utility model content
The purpose of the utility model is to provide the concrete chisels of a kind of mitigation user's hand burden, raising usage comfort
Hair machine.
To achieve the above object, following technical scheme is proposed:
A kind of concrete bush hammer, including dabbing head, casing and handle, identical side is provided with dabbing on handle
Top lug, lower part lug, support frame and shock absorber part, the upper end of support frame and top lug are rotatablely connected；One end of shock absorber part
It is rotatablely connected with support frame, the other end and lower part lug are rotatablely connected.
The principles of the present invention are: the support for being used to support dabbing machine is provided on the handle ipsilateral with dabbing
Frame, in use, the bottom of dabbing head and support frame support on the ground, when user catches handle replacing dabbing region
When, the weight of dabbing machine can be dispersed in the both ends of handle, in addition, shock absorber part is also provided between support rod and handle, damping
What part can continue is compressed and is stretched, and the concussion generated when dabbing head and concrete surface shock to handle can be absorbed, accelerate
The decaying of handle vibration.
The advantageous effects of the utility model are:
1. being provided with support frame, the burden of hand when using dabbing machine is alleviated.
2. being equipped with shock absorber part, the vibration generated when dabbing head and concrete surface shock to handle is alleviated, is increased
The comfort level of gripping.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model concrete bush hammer.
Attached drawing 2 is the enlarged drawing in Fig. 1 at A.
In figure: dabbing head 1, casing 2, handle 3, top lug 4, lower part lug 5, support frame 6, telescopic rod 7, spring 8, on
Plunger 9, lower plunger 10, pulley 11, handrail 12.
Specific embodiment
A kind of concrete bush hammer of the utility model is further illustrated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of concrete bush hammer, including dabbing head 1, casing 2 and handle 3, which is characterized in that handle 3
Upper side identical with dabbing head 1 is provided with top lug 4, lower part lug 5, support frame 6 and shock absorber part, the upper end of support frame 6
It is rotatablely connected with top lug 4；One end of shock absorber part and support frame 6 are rotatablely connected, and the other end and lower part lug 5 are rotatablely connected.
The support frame 6 for being used to support dabbing machine is provided on the handle 3 ipsilateral with dabbing head 1, in use, chisel
The bottom of burr 1 and support frame 6 is supported on the ground, and when user catches handle 3 to replace dabbing region, the weight of dabbing machine can
To be dispersed in the both ends of handle 3, the burden of hand when using dabbing machine is alleviated；In addition, also being set between support rod and handle 3
Shock absorber part is set, what shock absorber part can continue is compressed and stretched, to handle when dabbing head 1 and concrete surface shock can be absorbed
3 concussions generated, the decaying for accelerating handle 3 to shake increase the comfort level of the gripping of handle 3.
As shown in Figure 1 and Figure 2, in this embodiment, shock absorber part includes telescopic rod 7 and spring 8, the both ends of telescopic rod 7
It is respectively arranged with plunger 9 and lower plunger 10, upper plunger 9 and lower plunger 10 are respectively hinged at by pin screw bolt and nut in support frame
6 and lower part lug 5 on, 8 sets of spring is in 7 outside of telescopic rod and is arranged between upper plunger 9 and lower plunger 10；When dabbing head 1 with
When concrete surface is hit, under reaction force acts, dabbing chance generates very big vibration, when vibration is transmitted to handle 3, by
Between support frame 6 and handle 3, it is provided with shock absorber part, the telescopic rod 7 in shock absorber part can be by reciprocal under the action of spring 8
It compresses and stretches, the concussion generated when dabbing head 1 and concrete surface shock to handle 3 can be absorbed, the acceleration concussion of handle 3 declines
Subtract, improves the comfort level of the gripping of handle 3.
As shown in Figure 1, in this embodiment, the bottom end of support frame 6 is provided with pulley 11, and support frame 6 is for assisting
Dabbing machine is supported, it is more convenient when moving back and forth that pulley 11 facilitates dabbing machine, laborsaving.
As shown in Figure 1, in this embodiment, the rear end of casing 2 is provided with handrail 12.In 1 reciprocating percus-sion of dabbing head
When concrete surface, dabbing chance vertical tremor, user can proficiency gripping handle 3, another hand is placed on handrail 12, helps
In the work that dabbing machine is more stable.
It should be understood that embodiment is merely to illustrate the utility model rather than limitation the scope of the utility model.Furthermore it should manage
Solution, after reading the content taught by the present invention, those skilled in the art can make the utility model any various
Change and modification, such equivalent forms equally fall within the application the appended claims and are limited.
