Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of drilling devices, and in particular relates to a drilling device for municipal public works. Background Art
[0002] Drilling devices are mechanical tools used to drill holes in various materials and are widely used in manufacturing, construction, mining and other fields.
[0003] Municipal public works refer to the civil engineering, piping, and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heat, gardening, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities, and ancillary facilities.
[0004] During the construction of municipal utility projects, installation and drilling of related facilities are often necessary. Drilling sometimes requires working on hardened concrete, making it impossible to reserve the hole locations in advance. This results in significant resistance when workers hold the drilling device, making it difficult to easily control the position of the drilling device. This often results in skewed holes, which do not meet installation requirements and damage the concrete floor.
[0005] Therefore, a drilling device for municipal public works is provided to reduce the operating difficulty of workers and improve the quality of drilling. Summary of the Invention
[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a drilling device for municipal public works.
[0007] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows: A drilling device for municipal public works, comprising a drilling rig, a support system and a fixed pulley system; The drilling rig is slidably connected to a support system, and the support system regulates the freedom of movement of the drilling rig; The fixed pulley system is installed on the support system. One end of the fixed pulley system acts on the drilling rig, and the other end is a force-bearing end. When the force-bearing end of the fixed pulley system is acted upon by an external force, the drilling rig moves in the drilling direction.
[0008] The present invention regulates the freedom of movement of the drilling rig through the support system, so that the drilling rig can only move in the set direction, thereby ensuring the quality of the hole and avoiding the occurrence of skewed and twisted holes that do not meet installation requirements. In order to reduce the operating difficulty of the staff, a fixed pulley system is set up, and multiple staff members are required to cooperate. Specifically, one staff member holds the drill rig, and the other staff members operate the fixed pulley system. The staff members step down on the force-bearing end of the fixed pulley system with their feet. After the fixed pulley system changes the direction of the force, the force is transferred to the drill rig, causing the drill rig to move downward, thereby reducing the force that the staff holding the drill rig needs to apply. With the joint cooperation of multiple staff members, the drill rig can be easily controlled to perform downward drilling, avoiding the adverse situation caused by only one staff member drilling alone.
[0009] The beneficial effects of the present invention are as follows: the freedom of movement of the drilling rig is regulated by the support system, so that the drilling rig can only move in the set direction, thereby ensuring the quality of the hole, avoiding the occurrence of skewed and twisted holes, and failure to meet installation requirements; in terms of reducing the operating difficulty of the staff, a fixed pulley system is set up, and multiple staff members work together to reduce the operating difficulty.

[0011] The technical solutions of the present invention are described in detail below in conjunction with specific embodiments and their accompanying drawings. The embodiments described herein are specific embodiments of the present invention and are used to illustrate the concept of the present invention; these descriptions are explanatory and exemplary and should not be understood as limiting the embodiments of the present invention and the scope of protection of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the contents disclosed in the claims of this application and its specification, including technical solutions that adopt any obvious replacements and modifications to the embodiments described herein. Example 1
[0012] like Figure 1 As shown, this embodiment provides a drilling device for municipal public works, including a drilling rig 5, a support system and a fixed pulley system; The drilling rig 5 is slidably connected to the support system, and the support system regulates the freedom of movement of the drilling rig 5; The fixed pulley system is installed on the support system. One end of the fixed pulley system acts on the drilling rig 5, and the other end is the force-bearing end. When the force-bearing end of the fixed pulley system is acted upon by an external force, the drilling rig 5 moves in the drilling direction.
[0013] In this embodiment, the support system is used to regulate the freedom of movement of the drill rig 5 so that the drill rig 5 can only move in a set direction, thereby ensuring the quality of the hole and avoiding the occurrence of skewed and twisted holes that do not meet installation requirements. In order to reduce the operating difficulty of the staff, a fixed pulley system is set up, and multiple staff members are required to cooperate. Specifically, one staff member holds the drill rig 5, and the other staff members operate the fixed pulley system. The staff members step down on the force-bearing end of the fixed pulley system with their feet. After the fixed pulley system changes the direction of the force, the force is transferred to the drill rig 5, causing the drill rig 5 to move downward, thereby reducing the force that the staff holding the drill rig 5 needs to apply. With the joint cooperation of multiple staff members, the drill rig 5 can be easily controlled to perform downward drilling, avoiding the adverse situation caused by only one staff member drilling alone. Example 2
[0014] like Figure 1 、 2 As shown in Figure 4, this embodiment provides a drilling device for municipal public works. The difference from Example 1 is that the support system includes a base 1 and a bracket 2. There are two brackets 2 and they are fixed on the upper surface of the base 1. The bracket 2 forms a slide 202 through two rows of opposite retaining edges 201. The drilling rig 5 is connected to the mounting plate 4. A slider 3 is connected to each side of the mounting plate 4. The shape of the slider 3 is adapted to the slide 202. The base 1 is provided with a hollow 101 at the position corresponding to the downward exploration of the drilling rig 5.
[0015] In this embodiment, the base 1 provides a location for the mounting of the bracket 2. On the other hand, the base 1 has a large contact area with the surface to be drilled, which can improve the stability when placed. The hollow 101 on the base 1 can provide a passage space for the drilling rig 5 to drill. The sliding groove 202 formed by the rib 201 is used to regulate the sliding freedom of the slider 3 . Example 3
[0016] like Figure 5 、 6 As shown, this embodiment provides a drilling device for municipal public works. The difference from Example 2 is that the mounting plate 4 is provided with a mounting cavity 401 adapted to the drilling rig 5, and the upper surface of the mounting plate 4 is provided with two threaded columns 402, which are connected to the handle 6; the handle 6 is provided with an arc-shaped holding portion 61 and a soft pad 62, and the arc-shaped holding portion 61 is arranged with the concave surface facing upward, and the soft pad 62 is located in the concave surface of the arc-shaped holding portion 61.
[0017] In this embodiment, the mounting cavity 401 is used to place the drill 5. The drill 5 is locked on the mounting plate 4. After the handle 6 is fixed to the threaded column 402, the staff can control the height position of the drill 5 by pulling or pressing down the handle 6. The shape of the arc-shaped gripping portion 61 adapts to the shape of the human hand, which is convenient for gripping and not easy to slip out of the hand. The soft pad 62 in the concave surface deforms when under pressure, increasing the contact area with the human hand, thereby reducing the pressure and improving the comfort of human hand grip. Example 4
[0018] like Figure 1 、 3 As shown in Figure 5, this embodiment provides a drilling device for municipal public works. The difference from Example 2 is that the lower surface of the base 1 is provided with a hanging point 403 for attaching a fixed pulley system. There are two hanging points 403, and there are two sets of fixed pulley systems. The fixed pulley system includes a wire rope 14, a pedal 15, and several fixed pulleys 13 for changing the direction of force. Under the action of the fixed pulley 13, when the pedal 15 drives the wire rope 14 downward, the drilling rig 5 moves downward.
[0019] In this embodiment, the hanging point 403 is used to connect with the wire rope 14. When the drilling rig 5 needs to drill down, other staff members who do not operate the drilling rig 5 step on the pedal 15 with their feet to pull the wire rope 14 to move. When the fixed pulley 13 changes direction, the base 1 and the drilling rig 5 are driven downward by the wire rope 14, thereby drilling into the ground. Since the foot power is strong, it can provide greater auxiliary force for the downward drilling of the drilling rig 5, helping the drilling rig 5 to drill into some harder ground. Example 5
[0020] like Figure 1 、 8 As shown, this embodiment provides a drilling device for municipal public works. The difference from Example 2 is that it also includes a downward distance detection system. The downward distance detection system includes a guide rod 8, a locking block 9, a locking bolt 11, and a touch sensor 10. The guide rod 8 passes through the locking block 9. The locking bolt 11 is threadedly connected to the locking block 9. When the locking bolt 11 is screwed in, it interferes with the guide rod 8, and the locking block 9 is in a locked state. When the locking bolt 11 is withdrawn, it disengages from the guide rod 8, and the locking block 9 is in an unlocked state. The touch sensor 10 is installed below the locking block 9. The lower end of the guide rod 8 is fixed on the slider 3 and moves synchronously with the slider 3.
[0021] In this embodiment, the function of the downward distance detection system is to quantify the distance of the drill. The staff confirms the required drilling distance in advance and then adjusts the height of the locking block 9 on the guide rod 8 so that the distance between the detection end of the touch sensor 10 and the bracket 2 is the drilling distance. When the guide rod 8 moves downward along with the slider 3, the touch sensor 10 and the locking block 9 also move downward together. When the touch sensor 10 contacts the bracket 2, it indicates that the drill rig 5 has descended the required distance. This automatic drilling distance confirmation helps to improve the control of the hole depth and reduces the subsequent repeated drilling to achieve the hole depth standard. The position of the locking block 9 is adjusted by the locking bolt 11. When adjustment is required, the locking bolt 11 is loosened to allow the locking block 9 to slide relative to the guide rod 8. When the position of the locking block 9 needs to be fixed, the locking bolt 11 is tightened. After tightening, the locking bolt 11 applies pressure to the guide rod 8. Under the action of pressure, the maximum static friction force is increased, and the friction force is balanced with the gravity of the locking block 9, the locking bolt 11 and the touch sensor 10, so that the position of the locking block 9 can be kept fixed. Example 6
[0022] like Figure 1 、 7As shown, this embodiment provides a drilling device for municipal public works. The difference from Example 5 is that a guide sleeve 7 is installed in the slide groove 202, and the guide rod 8 passes through the slide sleeve 7; it also includes a signal indicator light 12, and the signal indicator light 12 emits a light signal when the touch sensor 10 touches the bracket 2.
[0023] In this embodiment, the sliding sleeve 7 is used to guide and straighten the guide rod 8. After all, the guide rod 8 is a rod-shaped object. When the guide rod 8 is long, it is easy to vibrate, and this vibration will affect the position of the locking block 9. The signal indicator light 12 is intended to use a light signal to indicate whether the touch sensor 10 is in place. Because during drilling, the noise of the drilling rig 5 will be very loud. If sound signals are used, the staff cannot accurately receive them. The light signal is very intuitive and is not affected by noise. Example 7
[0024] like Figure 2 、 9 As shown, this embodiment provides a drilling device for municipal public works. The difference from Example 2 is that the base 1 is further provided with a pedal 102 for the worker to apply his own weight, and the drill head of the drilling rig 5 is detachably connected to the protective cover 16.
[0025] In this embodiment, the pedal 102 is a standing area for the worker. When the worker stands on the pedal 102, he or she can apply his or her own weight to the base 1, thereby preventing the base 1 from moving during drilling and further improving stability. The protective cover 16 is a protective measure for the drilling machine 5 when drilling is not required to prevent the drill bit from being damaged.
[0026] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be covered by the claims of the present invention.
