Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a portable bracket punching device for bridges. Background Art

[0002] In the field of highway construction technology, bridges are important transportation infrastructure, and their construction quality is directly related to road safety and traffic efficiency. During the construction of bridges, the installation of pipe box supports is an indispensable link, and the stability of the pipe box supports depends on precise drilling and fixation.

[0003] The traditional method for installing pipe box brackets is to use bridge inspection vehicles and homemade pulleys. During the construction process, the space between the bridge guardrails is too small, the boom cannot be lowered when using a bridge inspection vehicle, and the construction cost is too high. The use of homemade pulleys is too slow and poses a great safety hazard. Therefore, a portable bridge bracket punching device is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art, such as inconvenient construction, high cost, low efficiency and potential safety hazards, and to propose a portable bridge bracket punching device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The lockhole that is formed on the upper end of the lifting plug is formed on the upper end of the lifting plug, and the lockhole that is formed on the lower end of the lifting plug is formed on the upper end of the lifting plug.

[0008] In a possible design, the limiting mechanism includes a limiting body, the bottom of the limiting body is fixedly connected to a base, the bottom of the base is provided with a groove, a plurality of rollers are rotatably connected in the groove via a rotating shaft, the bottom of the rollers are in contact with the top of the mounting tube, four penetrating fixing holes are provided on one side of the upper frame, and the same fixing pin is slidably connected in two corresponding fixing holes, and the fixing pin slides through the limiting body.

[0009] In a possible design, a plurality of adjustment holes for adjusting the height of the limiting mechanism are opened on one side of the limiting body, and the plurality of adjustment holes are symmetrically distributed on the left and right, and the two fixing pins slide through a pair of corresponding adjustment holes.

[0010] In a possible design, two penetrating slides are opened on one side of the mounting tube, and straps for binding and fixing the electric hammer are provided in the slides. The length of the slides is greater than the width of the straps, and the straps can be adjusted left and right in the slides.

[0011] In a possible design, a connecting piece is fixedly connected to the bottom of the side of two corresponding inner sleeves close to the mounting plate, and an operating handle for operating the device is fixedly connected to the top center of the connecting piece.

[0012] In a possible design, a switch for controlling the start and stop of the electric hammer is provided on the top of one side of the operating handle, and the switch is connected to the electric hammer through an electric wire.

[0013] In this application, when people need to use this device, they first fix the electric hammer to the mounting plate with bolts, then tie the electric hammer with two straps, then set up the device between two bridge guardrails, and adjust the position of the electric hammer by inserting the fixing pin into different adjustment holes, then press the switch and pull the operating handle in the direction close to the operator, and then the operating handle drives the two connecting mechanisms connected to it to rotate along the pin shaft, thereby pushing the lower frame and driving the mounting plate to push the electric hammer in the direction away from the operator. At this time, the mounting tube will maintain horizontal movement under the restriction of the limit mechanism, and at the same time the outer sleeve and the inner sleeve will slide and retract, and under the pull of the tension spring, the outer sleeve and the inner sleeve will be separated, so that the lower frame is also in horizontal movement, thereby ensuring that the electric hammer always remains in a horizontal state during work, and then repeatedly push and pull the operating handle until the punching work is completed, then turn off the switch and take away the device.

[0014] In the utility model, the portable bridge bracket punching device has a compact and flexible overall structure through the cooperation of the lower frame, the upper frame and multiple connecting mechanisms, and can be placed in the narrow gap between bridge guardrails to complete the punching operation. The outer sleeve and the inner sleeve in the connecting mechanism are connected by a pin shaft and a tension spring, and the fixing pin is fixed through the adjustment hole. This not only ensures the stability of the structure, but also allows the user to adjust the punching height according to needs, thereby greatly improving construction efficiency.

[0015] In the utility model, the portable bridge bracket punching device can be used to bind and fix the electric hammer through the slide and straps provided on the mounting tube, and the position of the straps can be adjusted as needed to accommodate electric hammers of different sizes and weights. In addition, the switch provided on the operating handle directly controls the start and stop of the electric hammer, making the operation more convenient and further improving the construction efficiency.

[0016] In the utility model, the portable bridge bracket drilling device can ensure that the electric hammer remains horizontal and stable during drilling through the contact between the roller and the installation pipe through the setting of the limiting mechanism, thereby improving the drilling accuracy;

Each connecting mechanism 3 is composed of an outer sleeve 15 and an inner sleeve 16. The outer sleeve 15 is rotatably connected to the inner wall of one side of the lower frame 1 through a second pin 18. Both ends of the second pin 18 are fixed with a second stopper 27 to prevent the outer sleeve 15 from falling off. The inner sleeve 16 is rotatably connected to the inner wall of one side of the upper frame 2 through a first pin 17. Both ends of the first pin 17 are also fixed with a stopper 26 to ensure the stability of the connection. The outer sleeve 15 is sleeved on the outside of the inner sleeve 16, and the two are slidably connected to achieve height adjustment. In order to maintain the elasticity of the connecting mechanism 3, the first pin 17 and the second pin 18 are connected by a tension spring 19. The tension spring 19 is located inside the outer sleeve 15 and the inner sleeve 16 to provide the necessary reset force;

Two slideways 11 opened on one side of the mounting tube 10 are provided with straps 12. The straps 12 are used to further fix the electric hammer 9 to prevent it from shaking during operation. The width of the straps 12 is less than the length of the slideway 11 and can be adjusted left and right in the slideway to accommodate electric hammers of different sizes.

[0027] The limiting mechanism 4 is composed of a limiting body 20, a base 21, a roller 23 and a fixing pin 5. A base 21 is provided at the bottom of the limiting body 20, and a roller 23 is rotatably connected in a groove 22 opened at the bottom of the base 21. The roller 23 contacts the top of the mounting tube 10 to ensure that the electric hammer 9 can remain level when the equipment is running. Four penetrating fixing holes 25 are provided on one side of the upper frame 2, which are fixed by sliding the fixing pin 5 through the adjustment hole 24 of the limiting body 20. The multiple settings of the adjustment hole 24 allow the user to adjust the height of the limiting mechanism 4 as needed to adapt to different working conditions.
