[0002] During the construction of prefabricated bridges, the cap beam and pier column are often designed to be connected by grouting sleeves. The top of the pier column and the bottom of the cap beam at the connection point need to be roughened, and the bottom of the cap beam often needs to be chiseled from the bottom up.

[0003] In the prior art, it is necessary to hold the top hand-held operating rod of the walking type roughening device and press one end of it, so as to use the lever principle to press the telescopic roughening head set on the other end of the top hand-held operating rod tightly to the bottom of the prefabricated cap beam. When the telescopic roughening head is roughening, a reverse impact force will be generated between the telescopic roughening head and the bottom of the prefabricated cap beam.

[0046] Specifically, Figure 1 In one embodiment, the chiseling assembly 10 includes a connecting sleeve 11, a top hand-held operating rod 12, and a chiseling head 13.

Among them, the first frame 21, one end of which is fixed on the moving assembly 30; the second frame 22, one end of which is fixed on the moving assembly 30, the second frame 22 and the first frame 21 are arranged opposite to each other in the first direction, one end of the second frame 22 overlaps with one end of the first frame 21, and is fixed on the moving assembly 30; the third frame 23 extends along the first direction and is arranged on the other end of the first frame 21 and the second frame 22; the first frame 21, the second frame 22 and the third frame 23 are configured as a tripod, and the connecting sleeve 11 is sleeved on the third frame 23.

[0051] In the above configuration, the support frame 20 is configured as a tripod structure, which can improve the structural strength of the support frame 20, thereby ensuring that it can support the haircutting assembly 10, and further ensuring that the haircutting assembly 10 can work normally.

[0052] Specifically, Figure 1 In one embodiment, the support frame 20 further includes a transverse support beam 24 , which is disposed between the first frame 21 and the second frame 22 to enhance the overall structural strength of the support frame 20 .

[0053] Specifically, Figure 1 In one embodiment, the transverse support beam 24 is extended along the first direction.

[0054] Specifically, Figure 1 In one embodiment, the first frame 21, the second frame 22, the third frame 23 and the transverse support beam 24 are all made of steel pipes.

[0055] Specifically, Figure 1 In one embodiment, the moving assembly 30 includes a bracket 31 and a bottom steering wheel 32. The bracket 31 has one end connected to the supporting frame 20; the bottom steering wheel 32 is arranged on the other end of the bracket 31, and the bottom steering wheel 32 can move on the ground.

[0056] Specifically, Figure 1 In one embodiment, the support 31 includes a first T-shaped frame 311 and a second T-shaped frame 312. The first T-shaped frame 311 has one end connected to the support frame 20, and the other end of the first T-shaped frame 311 is provided with a bottom steering wheel 32; the second T-shaped frame 312 has one end connected to one end of the first T-shaped frame 311, and the other end of the second T-shaped frame 312 is provided with a bottom steering wheel 32.

[0057] Specifically, Figure 1 In one embodiment, the first T-shaped frame 311 and the second T-shaped frame 312 are both welded from two steel pipes.

[0058] Specifically, Figure 1 In one embodiment, the first T-shaped frame 311 is formed by welding a vertical steel pipe and a horizontal steel pipe. Bottom steering wheels 32 are respectively provided at both ends of the horizontal steel pipe of the first T-shaped frame 311. The vertical steel pipe is welded to the support frame 20.

In this way, when the haircutting machine head 13 hammers the bottom of the prefabricated cap beam, a reverse impact force is generated, which acts on the haircutting machine head 13 and is transmitted to the other end of the top hand-held operating rod 12, and the direction is upward. At this time, the tension spring 41 has a tensioning function on the other end of the top hand-held operating rod 12, and the tensioning force can offset part of the reverse impact. Thereby realizing the buffering function of the buffer assembly 40. Thereby avoiding the reverse impact force driving the other end of the top hand-held operating rod 12 to tilt upward and fall out of the hand. Then it leads to the problem that the walking haircutting device cannot work normally.

[0061] Embodiment 2

[0062] like Figure 2 As shown, the utility model also provides a walking type roughening device for prefabricated cap beams. The walking type roughening device for prefabricated cap beams has the following differences from the walking type roughening device in the first embodiment: the first T-shaped frame 311 is configured as a telescopic frame, and the second T-shaped frame 312 is configured as a telescopic frame. The second T-shaped frame 312 can be telescopic in the third direction. The first T-shaped frame 311 can be telescopic in the second direction.

[0063] It should be noted that the first T-shaped frame 311 can be extended and retracted in the second direction. This makes the overall height of the walking type roughening device adjustable. Therefore, it can be suitable for prefabricated cap beams of different heights. That is, the walking type roughening device can roughen the bottom of prefabricated cap beams of different heights. In addition, the second T-shaped frame 312 can be extended and retracted in the third direction. This makes the overall length of the walking type roughening device adjustable. This makes it convenient to adjust the distance between the handle 14 and the roughening machine head 13. This ensures that the on-site operator maintains a certain safe distance from the roughening machine head 13. This improves the safety of the walking type roughening device.

[0064] Furthermore, if Figure 2 As shown, the first T-shaped frame 311 includes a horizontal steel pipe and a vertical steel pipe. The vertical steel pipe is configured as a telescopic structure. It includes an inner tube, an outer tube, and a locking screw. The inner tube is slidably disposed in the outer tube, and an axial sliding groove is provided on the inner and outer tubes. The locking screw is passed through the axial sliding groove of the inner and outer tubes to lock the relative positions of the inner and outer tubes.

[0065] Furthermore, if Figure 2As shown, the second T-shaped frame 312 includes a horizontal steel pipe and a vertical steel pipe. The horizontal steel pipe is configured as a telescopic structure. It includes an inner tube, an outer tube and a locking screw. The inner tube is slidably disposed in the outer tube, and an axial slide groove is provided on the inner and outer tubes. The locking screw is passed through the axial slide groove of the inner and outer tubes to lock the relative positions of the inner and outer tubes.

[0066] The other structures of the second embodiment are the same as those of the first embodiment and will not be described in detail here.

[0067] It should be noted that the walking roughening device for the bottom of the prefabricated cap beam in the present application is independently designed and used, and the entire frame is welded. The device uses the bottom steering wheel, the middle hand-held rod (the horizontal steel pipe in the second T-frame 312), the top hand-held operating rod and the movable bearing (connecting sleeve 11) as the moving and operating device, and the welded frame as the supporting and force-bearing device. The bottom of the prefabricated component can be roughened in a limited space by manually pushing and pulling and rotating the above-mentioned operating rod up and down.

[0068] The walking type hair cutting device in the present application has the following advantages:

[0069] 1. The structure is simple, and the low-end contact part can be roughened in time after the prefabricated cap beam meets the roughening requirements. The construction process is simple, and the workers can directly push, pull, and rotate up and down to roughen the contact surface, which is highly efficient.

[0070] 2. The device has a wide range of applications and is also suitable for roughening the bottom of other prefabricated components. The construction process is simple and can be completed by direct welding, which saves costs and has a good roughening effect.
