Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and particularly relates to a vertical portable drilling device and a usage method thereof. Background Art

[0002] In modern construction projects and decoration operations, vertical drilling (especially drilling in the top beam) is a basic and frequent operation process. Currently, manually holding an electric drill for vertical drilling is still a relatively common construction method.

[0003] From a mechanical perspective, due to the lack of a stable support system in this method, it is difficult for the operator to maintain the electric drill in a strictly vertical state for a long time. According to the principle of force balance, a small deviation in the force applied by the hand when holding the electric drill will cause the electric drill to receive a component force in a non-vertical direction, resulting in the drilling direction deviating from the predetermined trajectory, causing drilling perpendicularity errors, and seriously affecting the accuracy and quality of subsequent component installation, pipeline embedding and other processes. For vertical drilling operations at high altitudes or in deep holes, not only does the labor intensity greatly consume the operator's physical strength, resulting in low construction efficiency, but also during the operation process, due to human fatigue and difficulty in precisely controlling the electric drill, there are relatively high safety risks, such as the electric drill slipping off and falling.

[0004] Therefore, it is very necessary to invent a vertical portable drilling device and a usage method to solve the above problems. Summary of the Invention

[0020] To enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the accompanying drawings.

[0021] The present invention provides a vertical portable drilling device as shown in Figures 1-5 , which includes a floor rod 1, a holding rod 11, a main rod 12 and a connecting rod 13. The floor rod 1 and the main rod 12 are distributed in parallel, the main rod 12 and the connecting rod 13 are distributed in parallel, and a rhombic closed frame is formed around the ends of the main rod 12 and the connecting rod 13 and the floor rod 1 and the holding rod 11. A hydraulic cylinder 5 is fixedly installed at the top of the main rod 12, and the output end of the hydraulic cylinder 5 is fixedly connected with a screw rod 14. A cross frame 15 is arranged on the screw rod 14, and the tail end of the cross frame 15 is movably sleeved on the screw rod 14. A fixing component 2 is jointly arranged on the screw rod 14 and the cross frame 15 for installing a drill mechanism. A support mechanism 3 is arranged at the bottom of the floor rod 1; The fixing component 2 includes a high-pressure clamp 21 detachably installed on the top of the lead screw 14. At least two U-shaped clamps 22 are arranged on the front of the cross frame 15. Two nuts 23 are threadedly installed on the outer side of the lead screw 14, and the two nuts 23 are respectively located above and below the tail end of the cross frame 15. The support mechanism 3 includes a base 31 arranged below the floor rod 1, and a power supply device 4 is arranged outside the base 31.

[0022] In this embodiment, the floor rod 1 and the main rod 12 are vertically arranged, and the connecting rod 13 and the holding rod 11 are horizontally arranged, jointly forming a rhombic closed frame. As an adjustable support mechanism, it is movably connected by bolts and nuts. This structure provides a stable basic framework for the entire drilling device. The operator controls the holding rod 11 to ensure that the overall structure of the device is not easily deformed during the drilling process and to ensure the perpendicularity of the drilling. The holding rod 11 is convenient for the operator to hold by hand, conforms to ergonomics, is convenient for applying force and controlling the device, and reduces the labor intensity. Moreover, by using the operator to control the holding rod 11, the lifting of the electric drill installed at the top of the main rod 12 can be controlled. At the same time, the movably connected structure enables the device to be appropriately disassembled or folded during transportation and storage, reducing the occupied space. The upper ends of the floor rod 1 and the main rod 12 and the connecting rod 13, and the lower ends and the holding rod 11 are movably connected by bolts and nuts, allowing the angles and positions of the components to be adjusted within a certain range to adapt to different construction scenarios and drilling requirements.

[0023] When the adjustable support mechanism composed of the floor rod 1, the main rod 12, the connecting rod 13 and the holding rod 11 is in use, loosen the locking nut and press the end of the holding rod 11. At this time, the main rod 12 remains vertical and moves upward along an arc trajectory, that is, the drill bit of the electric drill moves along an arc trajectory. It is particularly suitable for drilling operations on the top beam structures of arched roof beams and inclined beams of sloping roofs. When multiple holes need to be drilled continuously, rapid positioning and adjustment can be achieved, greatly improving the work efficiency and ensuring the drilling accuracy.

[0024] In this embodiment, the adjustable and stable support composed of the floor rod 1, the holding rod 11, the main rod 12 and the connecting rod 13 can be used independently. That is, after installing the electric drill mechanism on its top, wrap an anti-slip pad around the bottom of the floor rod 1, place it and adjust the angle, and then rapid drilling operations can be carried out. The whole device is portable and easy to operate.

[0025] Furthermore, in the above technical solution, the tail end of the high-pressure clamp 21 is fixedly installed at the top of the lead screw 14 through bolts.

The upper ends of the landing rod 1 and the main rod 12 are movably connected to both ends of the connecting rod 13 by bolts and lock nuts, and the lower parts of the landing rod 1 and the main rod 12 are movably connected to the front end of the holding rod 11 by bolts and lock nuts for the movable adjustment and locking of the diamond-shaped frame.

[0027] Furthermore, in the above technical solution, a positioning groove 33 is provided at the middle position of the base 31, the lower end of the landing rod 1 is adaptively inserted into the positioning groove 33, support rods 32 are rotatably installed at the middle positions around the base 31, and limiting sleeves 16 are fixedly installed around the lower part of the landing rod 1. The upper ends of the four support rods 32 are all inclined and abutted against the lower part of the corresponding limiting sleeve 16.

[0028] Furthermore, in the above technical solution, the power supply device 4 is composed of a base 41 and a storage battery 43. Battery compartments 42 are provided around the upper end of the base 41, and a storage battery 43 is inserted into each battery compartment 42 in an embedded manner. The bottom of the storage battery 43 is electrically connected to the bottom of the battery compartment 42 through electrical contacts. For the convenience of moving the power supply device 4, a plurality of self-locking rollers can be provided at the bottom of the base 41.

[0029] Furthermore, in the above technical solution, a socket 44 is fixedly installed at a corner of the upper surface of the base 41. The electrical contacts inside the base 41 are electrically connected to the socket 44 through wires, and a groove 45 is provided at the upper end of the base 41. The base 31 is placed in the groove 45. During use, in order to improve the stability of the device, a counterweight can be added to the base 41, and the base 31 and the base 41 can be connected and combined.

[0030] In this embodiment, the base 41 serves as the main body of the power supply device 4. The battery compartment 42 is provided for embedding the storage battery 43. The socket 44 is provided and the electrical contacts are electrically connected to the socket 44 through wires to provide power supply for the drilling tool. The groove 45 is provided to place the base 31, making the combination of the power supply device 4 and the support mechanism 3 closer and enhancing the overall stability. The electrical contacts connect the bottom of the battery compartment 42 and the storage battery 43, which is convenient for replacement and installation, ensuring the continuity and stability of power supply and being applicable to construction sites without external power sources. Moreover, the bottom area of the base 41 is larger. When the base 31 is placed in the groove 45 of the base 41, the rotation angle of the support rods 32 around the base 31 is restricted, maintaining the support effect of the support rods 32. At the same time, the contact area between the bottom of the base 41 and the ground is also increased. The socket 44 facilitates the connection of the wire of the electric drill to the power supply device 4 for power supply. It is fixedly installed at a corner of the upper surface of the base 41 and is connected to the electrical contacts through wires, facilitating the plugging and unplugging of electrical equipment such as drilling tools and realizing power transmission to meet the power consumption requirements of drilling operations.

[0031] Furthermore, in the above technical solution, the base 31 and the support rod 32 are both made of solid metal materials, the base 41 is made of plastic materials, and the outside of the base 41 is wrapped with a rubber shell.

[0032] In this embodiment, the base 41 is made of plastic materials, which can not only reduce the weight of the base 41, thus facilitating the carrying and moving of the base 41, but also has wires installed inside the base 41 and an external storage battery 43, thereby ensuring the safety performance of the base 41. The rubber shell wrapped outside the base 41 further prevents the base 41 from leakage, and at the same time can also play a role in protecting the base 41, avoiding excessive wear of the base 41 and causing damage to the base 41.

[0033] Furthermore, in the above technical solution, the floor rod 1 and the main rod 12 are vertically arranged, and the length of the floor rod 1 is greater than that of the main rod 12, and the length of the grip rod 11 is greater than that of the connecting rod 13.

[0034] Furthermore, in the above technical solution, the floor rod 1 is set as a telescopic rod structure for adjusting the working height of the drilling mechanism. Specifically, the telescopic adjustment part of the floor rod 1 is located between the grip rod 11 and the limit sleeve 16; as an alternative embodiment, different lengths of the floor rod 1 can also be replaced to meet the drilling requirements of different heights.

[0035] A hydraulic driving mechanism for providing driving force is arranged at the input end of the hydraulic cylinder 5.

[0036] A usage method of a vertical portable drilling device is as follows: Step 1, lay out the operation base: Place the power supply device 4 below the area to be drilled, and install the base 31 in the groove 45. Step 2, assemble the drilling device: Hinge the floor rod 1, the grip rod 11, the main rod 12 and the connecting rod 13 into an adjustable support mechanism through bolts. The top of the main rod 12 is sequentially installed with a hydraulic cylinder 5, a lead screw 14 and a fixing component 2 from bottom to top. The drilling mechanism is installed on one side of the cross frame 15 through the fixing component 2. At this time, the drill bit of the drilling mechanism is vertically upward and extends to the top of the high-pressure clamp 21. Step 3, locate the drilling points and the running track, specifically: Step 3.1, combine the assembled structure of the drilling device in Step 2 with the operation base in Step 1, insert the bottom end of the floor rod 1 into the positioning groove 33, and support it with the cooperation of the support rod 32 and the limit sleeve 16. Step 3.2, determine the positions of multiple drilling points, and connect the drilling points distributed on the same straight line to draw an auxiliary line as the running track of the drilling mechanism, and pre-tighten the locking nut on the bolt. Step 3.3: Move the base 41 to make the holding rod 11 and the connecting rod 13 parallel to the drawn auxiliary line, and make the drill bit of the drill mechanism located directly below the first drilling point on the auxiliary line; Step 4: Perform power configuration: Insert the storage battery 43 into the battery compartment 42 so that the bottom electrical contact supplies power to the socket 44, and the drill mechanism and the hydraulic drive mechanism are powered on; Step 5: Drilling operation: Turn on the switch of the drill mechanism, and control the output end of the hydraulic cylinder 5 of the hydraulic drive mechanism to push the drill bit of the drill mechanism upward to vertically drill into the drilling point; After drilling, withdraw the drill bit, temporarily turn off the power, loosen the locking nut, press down the end of the holding rod 11, position the drill bit at the next drilling point and then pre-tighten the locking nut again, repeat the process of controlling the drill bit to feed upward for drilling, and so on until all the drilling points on the auxiliary line are drilled; Move the base 41, draw the auxiliary line again, and continue drilling on the new running track.

[0037] Specifically, install the electric drill at the upper end of the lead screw 14, and use the high-pressure clamp 21 to clamp and fix the part of the electric drill near the drill bit at the front end. The cross frame 15 can be adjusted up and down in position on the lead screw 14 through the nut 23. Then, according to the size of different models of electric drills, that is, the position of the handle of the electric drill, adjust the position of the cross frame 15, and then use the U-shaped clamp 22 on the front of the cross frame 15 to fix the handle of the electric drill, so as to fix the position of the electric drill and ensure the stability of subsequent electric drill drilling. The multiple connecting parts arranged on the front of the cross frame 15 and the multiple symmetrical through holes on the connecting parts facilitate replacing the U-shaped clamps 22 of different sizes according to different sizes of electric drills, and then can fix the handles of electric drills of different sizes.

[0038] Insert the lower end of the floor rod 1 into the positioning groove 33 in the middle of the base 31 to ensure a tight fit. Then unfold the support rods 32 around the base 31 so that their upper ends abut against the lower part of the limiting sleeve 16 below the floor rod 1 to form a stable support. Connect the main rod 12, the connecting rod 13, and the holding rod 11 to the floor rod 1 by bolts at the corresponding positions to form a rhombic closed frame as an adjustable support mechanism, and tighten the bolts to ensure firm connection. Insert the storage battery 43 into the battery compartment 42 of the base 41, and pay attention to good connection of the bottom electrical contact. Place the base 31 in the groove 45 of the base 41. Fix the lead screw 14 on the top of the main rod 12, movably sleeve the tail end of the cross frame 15 on the lead screw 14, install the high-pressure clamp 21 on the top of the lead screw 14, select a suitable U-shaped clamp 22 according to the size of the electric drill, and install it on the front connecting part of the cross frame 15 through a nut. Install the electric drill at the upper end of the lead screw 14, and first use the high-pressure clamp 21 to clamp the part of the electric drill near the drill bit at the front end. By rotating the nut 23, adjust the position of the cross frame 15 on the lead screw 14 so that the U-shaped clamp 22 on the cross frame 15 aligns with the handle of the electric drill, and then use the U-shaped clamp 22 to fix the handle of the electric drill.

[0039] The operator holds the holding rod 11, moves the device to the drilling position, and adjusts the device so that the drill bit is aligned with the predetermined drilling point. Keep the holding rod 11 stable, slowly start the drill, and start the drilling operation. During the drilling process, by controlling the holding rod 11, control the lifting of the drill as needed to keep the drill drilling vertically and stably.
