Description

Technical Field

[0001] The utility model relates to the technical field of grounding body installation, in particular to a hammer-type grounding body installation device. Background Art

[0002] A large number of electrical equipment and systems are often used in the fields of power, construction, chemical and petroleum industries. In order to prevent lightning strikes from damaging electrical equipment and systems, it is often necessary to install a lightning protection system, in which the grounding body is a very important component of the lightning protection system. The grounding body is a metal conductor buried underground at a suitable depth and has certain requirements for cross-section and resistance. It provides electrical connection between electrical equipment, buildings and the earth through direct contact with the soil. It is used to lead lightning current and conduct the current into the ground, thereby protecting the safety of buildings, internal equipment and human life.

[0003] At present, there are three methods for installing grounding electrodes: burying them underground after manual hammering or manual excavation, driving them in by vibration, and inserting them in holes in the ground using drilling equipment. The specific advantages and disadvantages are as follows: (1) Driving the grounding electrode into the ground by manual hammering or manual excavation. These methods are simple to operate and are generally suitable for conditions with relatively soft soils. For hard soils or rocky soils, the installation efficiency or effect is not high and it is time-consuming and labor-intensive. (2) Driving the grounding electrode into the ground by vibration. It uses the principle of vibration and uses a vibrating hammer to generate strong vibration force to loosen the grounding electrode in the soil, making it easier to drive it in. However, for some special landforms, such as the Gobi Desert, where the soil has a high stone content and is relatively hard, the vibration method is often unable to effectively drive the grounding electrode into the deep soil under such soil conditions, resulting in unsatisfactory grounding effect. (3) The installation method is to drill a hole in the ground with a drilling device and then insert the grounding body. However, during the installation process, steel bars need to be laid in the hole, and concrete needs to be poured after the grounding body is inserted. However, in the Gobi Desert area where transportation is not convenient, the harsh environment and inconvenient transportation make the supply of equipment and materials difficult, the use scenarios are limited, and the installation cost is often high.

[0004] In the prior art, the utility model patent with patent number 202022751938.0 discloses a reciprocating vibration ground rod assisted drilling machine, which includes a mechanical transmission part, a casing, a power part (power supply, motor) and a control part; the scheme uses a motor to drive the gear movement, and then drives the piston and the piston hammer to continuously vibrate up and down to achieve the function of drilling the ground rod into the ground, which has the characteristics of simple operation and wide application scenarios. However, the device is driven by a motor and needs to be equipped with an additional power supply, which is inconvenient to carry. In addition, when the device is in use, the verticality of the grounding body installation needs to be manually controlled. The vibration generated by the piston hammer when hammering the grounding rod is difficult to ensure the consistency of the verticality of the grounding rod, resulting in poor installation efficiency and effect.

[0005] Therefore, it is necessary to propose a new type of grounding body installation device to solve the above problems. Utility Model Content

[0006] In order to solve the problems in the prior art that a separate power supply is required, the device is inconvenient to carry, and the grounding verticality is difficult to ensure, resulting in poor installation effect, the utility model provides a hammer-type grounding body installation device.

[0007] In order to achieve the above objectives, the following technical solutions are provided:

[0008] A hammer-type grounding body installation device includes a slide, a base, a fuel engine and a hammer head. The slide is vertically installed on the base, and the fuel engine is slidably arranged on the slide through a bracket; a guide device for clamping the grounding body is provided on the base; the fuel engine is connected to a transmission housing, and the hammer head is vertically slidably arranged at the bottom of the transmission housing, and the output shaft of the fuel engine is connected to the hammer head through a reciprocating transmission mechanism in the transmission housing; and a grounding body connector is also included, which is slidably arranged at the bottom of the hammer head and connected to the transmission housing through a spring.

[0009] Furthermore, the reciprocating transmission mechanism includes a first bevel gear, a second bevel gear, a crankshaft and a piston connecting rod; the first bevel gear is coaxially fixedly connected to the output shaft of the fuel engine, the second bevel gear is fixedly connected to the rotating shaft of the crankshaft, one end of the piston connecting rod is rotatably mounted on the crank of the crankshaft, and the other end is rotatably connected to the hammer head.

[0010] Furthermore, the guiding device comprises two rotating rods rotatably mounted on the base, and pulleys are mounted on opposite ends of the two rotating rods.

[0011] Furthermore, a protective net is installed on the base.

[0012] Furthermore, a limiting device for fixing the bracket on the slide is provided on the side of the bracket.

[0013] Furthermore, handrails are installed on both sides of the transmission housing or the bracket.

[0014] Furthermore, moving wheels are installed under the base.

[0015] Furthermore, the moving wheel is installed on the base through a quick-loading mechanism, and the quick-loading mechanism includes a fork frame fixed on the rotating shaft of the moving wheel, one side of the fork frame is provided with a mounting hole and a limit rod, one end of the limit rod is rotatably installed on the other side of the fork frame through a pin; the other end of the limit rod is provided with a stopper.

[0016] The beneficial effects of the utility model are as follows: 1. A fuel engine is used to provide a power source for hammering the grounding body drill rod, and there is no need to carry an additional power supply device; it is portable and easy to use. 2. The top of the grounding body drill rod is installed on the grounding body connector, and the bottom is clamped on the guide mechanism on the base. In the process of hammering the grounding body drill rod, the fuel engine, the hammer head, and the grounding body connector can move downward along the slide and maintain verticality with the ground, thereby improving the installation effect. 3.

Compared with drilling installation, hammering installation does not require supporting materials or concrete pouring. Only the hammering method can make the grounding body and the soil layer tightly connected together, the installation process is faster, the equipment structure is simpler, safer and more efficient, and at the same time avoids the transportation difficulties of large equipment.

DETAILED DESCRIPTION

[0024] The hammer-type grounding body installation device of the utility model is further described below in conjunction with the embodiments.

[0025] like Figure 1 , Figure 2 As shown, a hammer-type grounding body installation device includes a slide 1, a base 2, a fuel engine 3 and a hammer head 4. The slide 1 is vertically installed on the base 2, and the fuel engine 3 is slidably arranged on the slide 1 through a bracket 5; a guide device for clamping the grounding body is provided on the base 2; the fuel engine 3 is connected to a transmission housing 6, and the hammer head 4 is vertically slidably arranged at the bottom of the transmission housing 6, and the output shaft 13 of the fuel engine 3 is connected to the hammer head 4 through a reciprocating transmission mechanism in the transmission housing 6;

[0026] The device uses a fuel engine 3 as a power source, and drives the hammer head 4 to move up and down in the transmission housing 6 through a reciprocating transmission mechanism, and places one end of the grounding body drill rod 25 at the bottom of the hammer head 4, and the other end is clamped on the guide device, so as to maintain the verticality of the grounding body drill rod 25 and the ground during the hammering process. The fuel engine 3 can be a gasoline engine or a diesel engine.

[0027] In this embodiment, a grounding connector 7 is also included. The grounding connector 7 is slidably disposed at the bottom of the hammer head 4 and is connected to the transmission housing 6 through a spring 8 .

[0028] One end of the grounding body drill rod 25 is installed on the grounding body connector 7, such as inserted into the hole at the bottom of the grounding body connector 7 or threadedly installed in the hole, and the other end is clamped on the guide device. The hammer head 4 reciprocates up and down in the transmission housing 6, continuously hammering the grounding body connector 7, and then driving the grounding body drill rod 25 into the ground. The spring 8 is used to connect the grounding body connector 7 with the transmission housing 6 as a whole. When the hammer head rises, the spring 8 can pull the upper half of the grounding body connector 7 into the transmission housing 6, so that it is relocated at the bottom of the hammer head 4. At the same time, it can also reduce the vibration generated to the outside of the device.

[0029] Among them, Figure 4As shown, the reciprocating transmission mechanism includes a first bevel gear 9, a second bevel gear 10, a crankshaft 11 and a piston connecting rod 12; the first bevel gear 9 is coaxially fixedly connected to the output shaft 13 of the fuel engine 3, the second bevel gear 10 is fixedly connected to the rotating shaft of the crankshaft 11, one end of the piston connecting rod 12 is rotatably mounted on the crank 14 of the crankshaft 11, and the other end is rotatably connected to the hammer head 4. The horizontal rotation of the output shaft 13 of the fuel engine 3 is converted into vertical rotation by the first bevel gear 9 and the second bevel gear 10, the first bevel gear 9 drives the second bevel gear 10 to rotate, and then drives the crankshaft 11 to rotate, and the piston connecting rod 12 rotates up and down with the crank 14 on the crankshaft 11, thereby driving the hammer head 4 to slide back and forth up and down at the bottom of the transmission housing 6.

[0030] like Figure 1 , Figure 2 As shown, a plurality of brazing holes 27 are provided on the base 2, and the base 2 is a metal base 2. The brazing holes 27 are formed by punching a metal plate, and the metal plate is welded to the metal base 2. The brazing holes 27 are used to insert brazing rods to fix the base 2 on the ground.

[0031] like Figure 5 , Figure 6 As shown, a protective net 17 is also installed on the base 2 to prevent the grounding body drill rod 25 from colliding with the ground and causing sand and gravel to splash when the grounding body drill rod 25 is hammered, thereby avoiding injuries to personnel.

[0032] like Figure 2 , Figure 6 As shown, the guide device includes two rotating rods 15 rotatably mounted on the base 2, and pulleys 16 are mounted on opposite ends of the two rotating rods 15. The rotating rods 15 rotate in opposite directions, and the pulleys 16 on both sides abut against each other. The depth of the slide groove between the pulleys 16 matches the diameter of the grounding body drill rod 25. One end of the grounding body drill rod 25 is mounted on the grounding body connector 7, and the other end is clamped between the pulleys 16 on both sides, so that the grounding body drill rod 25 can move downward along the pulleys 16, thereby playing a guiding role.

[0033] like Figure 2 As shown, a limiting device for fixing the bracket 5 on the slide 1 is provided on the side of the bracket 5. The limiting device includes a screw hole on the side of the bracket 5 and a rotating handle 18 at the screw hole. By rotating the rotating handle 18 and utilizing the position of the rotating handle 18 in the screw hole, the bracket 5 is clamped on the slide 1. By rotating the rotating handle 18 in the opposite direction, the bracket 5 can be released from the slide 1, so that the bracket 5 can slide freely up and down on the slide 1.

[0034] like Figure 1 , Figure 2As shown, handrails 19 are installed on both sides of the transmission housing 6 or the bracket 5. In this embodiment, the handrails 19 are installed at the bottom of the transmission housing 6. The handrails 19 are used to further stabilize the equipment by hand when hammering the grounding body drill rod 25, and to assist in applying force downward to prevent the reaction force from bouncing the bracket 5 upward.

[0035] like Figure 1 , Figure 2 As shown, a moving wheel 20 is installed below the base 2, and a handle 26 is provided on the upper part of the slide 1. When carrying this device, by tilting the device, a person pulls the handle 26 and uses the moving wheel 20 to move this device to a different position.

[0036] like Figure 3 As shown, the moving wheel 20 is installed on the base 2 through a quick-install mechanism. The quick-install mechanism includes a fork frame 21 fixed on the rotating shaft of the moving wheel 20. One side of the fork frame 21 is provided with a mounting hole 22 and a limit rod 23. One end of the limit rod 23 is rotatably installed on the other side of the fork frame 21 through a pin bolt; the other end of the limit rod 23 is provided with a stopper 24. Among them, the stopper 24 and the limit rod 23 are an integrally formed structure; the fork frame 21 includes a rotating cylinder in the middle and flaps on both sides of the rotating cylinder; when installing, first put the rotating cylinder of the fork frame 21 on the wheel axle of the moving wheel 20, then fold the flaps oppositely, insert one end of the limit rod 23 into the mounting hole 22 on one flap of the fork frame 21, and then use a pin bolt to fix the other end of the limit rod 23 on another flap of the fork frame 21. The quick-install mechanism has the characteristics of simple structure and convenient assembly and disassembly. After the device is moved to a position through the moving wheel, in order to improve the hammering installation effect, the moving wheel can be quickly removed and the base can be directly placed on the ground.

[0037] The use process of this device is roughly but not limited to the following specific steps:

[0038] After removing the moving wheels, place the device at the designated grounding body installation position and fix the device with four long drills; loosen the rotating handle 18 on the bracket 5, move the fuel engine 3 to a high position on the slide 1, and then tighten the rotating handle 18 on the bracket 5 to fix the bracket 5 on the slide 1; push the rotating rods 15 on both sides of the base 2 apart, place the grounding body drill rod 25, and clamp the grounding body drill rod 25 with the pulleys 16 on both sides; loosen the rotating handle 18 on the bracket 5 again, and connect the grounding body connector 7 to the grounding body drill rod 25. The fuel engine 3 is started, and the personnel put their hands on the handrail 19 to assist in applying downward force, and use the hammer head 4 that reciprocates up and down to drive the grounding body drill rod 25 into the ground; when the device reaches the bottom of the slide 1, the fuel engine 3 is turned off, the fuel engine 3 is moved to the highest position as a whole, and the rotating handle 18 on the bracket 5 is locked; the first grounding body drill rod 25 and the second grounding body drill rod 25 are connected through the connector; the above steps are repeated, and finally several grounding body drill rods 25 are continuously driven in; the long drill used for fixing on the base 2 is pulled out, and the device is moved to other positions.
