Description
Technical Field
The utility model relates to a hammer is drawn to earth bar belongs to power maintenance technical field.
Background
When an electric power enterprise carries out maintenance construction, all construction sites need to be provided with grounding rods, the grounding rods have the problem that the grounding rods cannot be pulled out after being nailed into the ground in winter, generally, the grounding rods are placed in situ and pulled out after being opened, but the grounding rods are basically pulled out by residents or wild stocking personnel walking early after being opened; or the earth rod is pulled out by the sledge hammer manually, but the sledge hammer cannot pull out the earth rod forcibly, the earth rod basically can be bent by smashing when the earth rod is pulled out in winter, the bent earth rod can not be reused when the next construction is carried out, and thus, the loss is brought to enterprises.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hammer is drawn to earth bar draws the gravity hammer through making a round trip and easily extracts the earth bar of nailing underground to having reduced scrapping and losing of earth bar, having improved the value of recycling of earth bar, easy operation is practical, convenient to carry, low price, practicality are strong, have reduced intensity of labour and cost, have improved work efficiency and use value, have solved the above-mentioned problem that exists effectively among the background art.
The technical scheme of the utility model is that: a grounding rod drawing hammer comprises a grounding rod, a connecting hook, a tension stroke rod, a gravity hammer baffle and a handle, wherein the handle is arranged at the top end of the tension stroke rod; the gravity hammer is arranged on the tension stroke rod in a vertically sliding mode, and a buffer spring is arranged between the gravity hammer and the top end of the bolt sleeve; the connecting hook is hooked on the bolt hole of the grounding rod grounding wire board.
The connecting hook is in threaded connection with the bottom end of the bolt sleeve and is fastened through a fastening bolt.
The utility model has the advantages that: the ground rod does not need to be pulled out after the ground rod is started, and the ground rod nailed into the ground is easily pulled out by pulling the gravity hammer back and forth, so that the scrapping and the loss of the ground rod are reduced, the recycling value of the ground rod is improved, the operation is simple and practical, the carrying is convenient, the price is low, the practicability is high, the labor intensity and the expenditure of a company are reduced, and the working efficiency and the utilization value are improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: the device comprises a ground rod 1, a connecting hook 2, a tension stroke rod 3, a gravity hammer 4, a gravity hammer baffle 5, a handle 6, a bolt sleeve 7, a buffer spring 8 and a ground wire plate 9.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
A grounding rod drawing hammer comprises a grounding rod 1, a connecting hook 2, a pulling force stroke rod 3, a gravity hammer 4, a gravity hammer baffle 5 and a handle 6, wherein the handle 6 is arranged at the top end of the pulling force stroke rod 3, the gravity hammer baffle 5 is arranged at the connecting part of the handle 6 and the pulling force stroke rod 3, the bottom end of the pulling force stroke rod 3 is in threaded connection with a bolt sleeve 7, and the connecting hook 2 is arranged at the bottom end of the bolt sleeve 7; the gravity hammer 4 is arranged on the tension stroke rod 3 in a vertically sliding mode, and a buffer spring 8 is arranged between the gravity hammer 4 and the top end of the bolt sleeve 7; the connecting hook 2 is hooked on the bolt hole of the grounding wire plate 9 of the grounding rod 1.
The connecting hook 2 is in threaded connection with the bottom end of the bolt sleeve 7 and is fastened through a fastening bolt. The connecting hook 2 is detachable from the bolt sleeve 7, and when the connecting hook 2 is damaged, only the connecting hook 2 needs to be replaced, so that the cost is saved. And the length of the connecting hook 2 can be selected according to the distance between the ground wire board 9 and the top end of the ground rod 1.
The utility model discloses a use method contains following step: the connecting hook 2 of the ground rod drawing hammer is hooked at a bolt hole of a ground wire plate 9 of the ground rod, an operator holds the handle 6 with one hand, slides the gravity hammer 4 up and down with the other hand, the gravity hammer 4 strikes the gravity hammer baffle plate 5 back and forth, the impact force of the upward striking gravity hammer baffle plate 5 drives the ground rod 1 to move upwards, and the operation is stopped until the ground rod is completely pulled out.
The buffer spring 8 prevents the bolt sleeve 7 from being broken when the gravity hammer 4 slides downward.
The gravity hammer 4 is of a cylindrical structure, and the middle part of the gravity hammer is provided with an annular groove, so that an operator can conveniently hold the gravity hammer 4 by hands, and the gravity hammer is prevented from being separated.
Draw the gravity hammer through making a round trip and easily extract the earth bar of nailing underground to reduced scrapping and losing of earth bar, improved the value of recycling of earth bar, easy operation is practical, convenient to carry, low price, practicality are strong, have reduced intensity of labour and cost, have improved work efficiency and use value.
