Description

Technical Field

[0001] The utility model belongs to the technical field of portable drilling rigs, and particularly relates to a movable building roof drilling device. Background Art

[0002] In the construction of mechanical and electrical installation projects, roof drilling is a key process for the installation of supports and hangers. However, the traditional construction method is limited by the building floor height and relies on construction workers to build scaffolding or movable platforms and carry electric hammers to work at heights. During the operation, the operator needs to hold the electric hammer by hand and apply force in an unnatural posture of looking up and raising the hand, resulting in the deviation of the body center of gravity and poor stability, and is prone to the risk of falling from a height. At the same time, the reaction force generated by the vibration of the electric hammer will exacerbate hand fatigue and further increase the probability of operation out of control.

[0003] Chinese Patent CN212526172U discloses an extended operation device for electric hammer operation, including a main rod and a secondary rod arranged vertically. There are at least two parallel connecting rods between the main rod and the secondary rod. The two ends of the connecting rod are rotatably installed on the main rod and the secondary rod. The end of one connecting rod extends outwards to form a handle. The top of the main rod is equipped with an electric hammer fixing component. An input power socket and an output power socket are arranged below the main rod. A power control switch is arranged on the handle. The power control switch is electrically connected to the input power socket and the output power socket and controls the on-off between the two. This patent uses a parallelogram structure to drive the main rod to move vertically to achieve fixed-point lifting, and the operation is simple. However, the electric hammer of this patent is fixed at the top of the main rod, and the connecting rod is located in the middle and lower part of the main rod, resulting in a large distance between the center of gravity of the electric hammer and the operation handle. When the electric hammer drills holes, it is prone to lateral shaking. Especially when the main rod is raised to a higher position or the length of the main rod is increased through an extension rod, the center of gravity of the main rod will move up. When drilling upwards, the shaking amplitude will increase significantly, affecting the drilling accuracy. At the same time, the height of the handle of this patent will change with the lifting of the main rod, lacking a fixed operation plane, and the power control switch is integrated on the handle, resulting in the operator needing to simultaneously complete the actions of holding the handle to exert force and pressing the switch with one hand. During this process, when bearing the reaction force of the electric hammer drilling, the hand needs to simultaneously consider the holding stability and the switch pressing operation, and is extremely prone to cause the electric hammer to shake due to uneven force distribution, thereby triggering the risk of accidental switch touch or drilling deviation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a movable building roof drilling device, which can solve the problem of lateral shaking caused by the center of gravity of the electric hammer being far from the operating rod and the excessive length of the main rod, and at the same time avoid the action conflict between single-handed holding and pressing the switch, eliminate the risk of working at heights, and improve the operation stability and drilling accuracy.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A movable building roof punching device includes a vertical support rod and a driven rod. Between the support rod and the driven rod, there are articulated parallel operating rods and connecting rods. The operating rods are located below the connecting rods. The length of the driven rod is less than that of the operating rod. A hammer drill is fixedly arranged on the driven rod, and the height of the driven rod is lower than the height of the top end of the hammer drill. The bottom of the hammer drill is arranged close to the connecting rod. A control switch is arranged on the support rod in cooperation with the hammer drill. The control switch is located below the operating rod. A moving base is arranged at the bottom of the support rod.

[0007] Wherein:

[0008] A rubber handle is arranged at one end of the operating rod away from the driven rod.

[0009] A fixed support is arranged at the upper end of the driven rod in cooperation with the hammer drill. The fixed support includes a bottom support. One end of the bottom support is vertically provided with an upright frame, and the upright frame is connected to the driven rod.

[0026] The present utility model will be specifically described and illustrated below in conjunction with embodiments.

[0027] Embodiment 1

[0028] As Figures 1-5 shown, the movable building roof drilling device of the present utility model includes a support rod 1 and a driven rod 10. An operating rod 11 and a connecting rod 12 which are parallel to each other are hinged between the support rod 1 and the driven rod 10. The operating rod 11 is located below the connecting rod 12. The length of the driven rod 10 is less than the length of the operating rod 11. An electric hammer 2 is fixedly arranged on the driven rod 10 and the height of the driven rod 10 is lower than the height of the top end of the electric hammer 2. The bottom of the electric hammer 2 is arranged close to the connecting rod 12. A control switch 3 is arranged on the support rod 1 in cooperation with the electric hammer 2. The control switch 3 is located below the operating rod 11. A moving base 4 is arranged at the bottom of the support rod 1. A universal wheel 5 is arranged on the moving base 4.

[0029] The electric hammer 2 is arranged close to the connecting rod 12, which can shorten the lever arm, reduce the reaction torque of the electric hammer 2, and enable the operator to offset the shaking by applying a smaller force through the operating rod 11, improving the working stability; the control switch 3 is separated from the operating rod 11, allowing the operator to hold the operating rod 11 with one hand and press the control switch 3 with the other hand, eliminating the action conflict between single-handed holding and pressing the switch, and reducing the risk of accidentally touching the switch or drilling deviation; the moving base 4 enables the device to move and turn flexibly, quickly adjust the working position, and reduce the labor intensity.

[0030] One end of the operating rod 11 far from the driven rod 10 extends outward, and a rubber handle 6 is arranged at the end of the operating rod 11 far from the driven rod 10. The rubber handle 6 can prevent the hand from slipping, reduce hand fatigue during operation, and improve the holding stability.

[0031] A fixed support 7 is arranged at the upper end of the driven rod 10 in cooperation with the electric hammer 2. The fixed support 7 includes a base 701, and a vertical frame 702 is arranged vertically at one end of the base 701. The fixed support 7 forms a three-dimensional support structure through the base 701 and the vertical frame 702, ensuring the fixed position of the electric hammer 2 during the drilling process, reducing shaking, and improving the drilling accuracy.

[0032] The electric hammer 2 includes a body 201, and a handle 202 and a drill bit 203 are arranged on the body 201 in cooperation.

[0033] The handle 202 is fixedly arranged on the base 701, and a clamping member one 8 is arranged on the base 701 in cooperation with the handle 202. The clamping member one 8 tightly clamps the handle 202 and the base 701 to prevent the electric hammer 2 from loosening due to vibration during operation.

[0034] The body 201 is fixedly arranged on the vertical frame 702, and a clamping member two 9 is arranged on the vertical frame 702 in cooperation with the body 201. The clamping member two 9 fixes the body 201 to the vertical frame 702, further restricting the shaking of the electric hammer 2, and forming a multi-directional fixation of the electric hammer 2 in cooperation with the clamping member one 8, improving the drilling stability and safety.

[0035] A control cable is arranged between the electric hammer 2 and the control switch 3. By arranging the control cable, the operator can remotely control the start and stop of the electric hammer 2 through the control switch 3.

[0036] Four universal wheels 5 are fixedly arranged at the bottom of the moving base 4.

[0037] The universal wheel 5 includes a wheel body 501, a support frame 502 is arranged on the wheel body 501 in cooperation, and a steering mechanism 503 is arranged on the support frame 502. The steering mechanism 503 can control the rotation direction of the wheel body 501, enabling the device to turn flexibly during movement.

[0038] The control switch 3 is provided with a power cord, and one end of the power cord away from the control switch 3 is plugged into a socket. The power cord provides a power source for the electric hammer 2. By turning the control switch 3 on and off, the power cord and the control cable transmit AC power to the electric hammer 2, driving the drill bit 203 to rotate and impact.

[0039] Working process and principle:

[0040] 1. Device Movement

[0041] The operator pushes the device, and the wheel body 501 of the universal wheel 5 can rotate 360 ​​degrees freely on the support frame 502 through the steering mechanism 503, so that the device can flexibly adjust the direction and quickly move to the position where the building roof is to be punched. After reaching the designated position, the device relies on the mobile base 4 to park stably.

[0042] 2. Height Adjustment

[0043] The operator stands at the side of the device, holds the rubber handle 6 with one hand, holds the support rod 1 with the other hand, and drives the driven rod 10 to rise steadily in the vertical direction by pressing down the operating rod 11, and accurately aligns the drill bit 203 of the electric hammer 2 with the drilling position of the top plate. In this process, the rubber handle 6 increases the friction of the hand, reduces the fatigue of the operator, and improves the stability of the grip.

[0044] 3. Punching operation

[0045] When the drill bit 203 of the electric hammer 2 is aligned with the target position, the operator maintains a stable grip on the rubber handle 6 with one hand and presses the control switch 3 on the support rod 1 with the other hand. The control switch 3 is connected to the external socket through the power cord, and electric energy is transmitted to the electric hammer 2 through the control cable, driving the drill bit 203 of the electric hammer 2 to rotate at high speed and generate an impact action to drill a hole in the building roof.

[0046] In this process, the handle 202 of the electric hammer 2 is fixed to the bottom bracket 701 of the fixed support 7 through the clamp part 1 8, and the body 201 of the electric hammer 2 is fixed to the stand 702 through the clamp part 2 9, forming a multi-directional fixation of the electric hammer 2. Since the bottom of the electric hammer 2 is close to the connecting rod 12, the distance between its center of gravity and the operating rod 11 is shortened, and the reaction torque generated by the electric hammer 2 during drilling is significantly reduced. In conjunction with the support rod 1 and the operating rod 11, the lateral shaking of the device is effectively suppressed, and the drilling accuracy is improved. At the same time, the control switch 3 is independently set on the support rod 1, avoiding the conflict between holding the operating rod 11 and pressing the control switch 3 with one hand at the same time, and reducing the risk of accidental touch.

[0047] 4. Hole Position Switching

[0048] After completing the operation of a single hole position, the operator releases the control switch 3, and the electric hammer 2 stops working. The position of the device is adjusted through the casters 5, and the operation of the next hole position can be continued without the operator climbing to a height or applying force in an unnatural posture, fundamentally eliminating the risk of falling from a height.
