Description

A height-adjustable grill

Technical field:

The utility model relates to a height-adjustable grilling pole.

Background technique:

With the development of society and economy, there are more and more construction and expansion projects of substation (distribution) substations, and the development of urban construction makes some substations (distribution) substations with relatively lower terrain need to be relocated or upgraded. Therefore, There are more and more installation tasks for electrical equipment such as isolating switches and lightning arresters, but the traditional installation methods in the past have the following disadvantages:

For the installation or replacement of independent ceramic parts such as isolating switches, insulating pillars, and lightning arresters, if cranes are used for hoisting, the cost of using vehicles is high, and in new substations, there must be enough site space to meet the needs of boom extension and maneuvering; For substation expansion or reconstruction work, it is also necessary to ensure a safe distance between the boom, wire rope, hoisting objects, auxiliary equipment, etc. Accompanied by a power outage, it may even require the busbar to stop running, causing economic losses; if the self-provided wooden independent pick-up pole is used for hoisting, in order to meet the traffic regulations on the transportation of super-long items, it will take time to apply for a special pass. If you rent an extended truck for transportation, then The cost is more paid, and it takes up a lot of space in the storage room.

Invention content:

In order to overcome the defects of the prior art, the purpose of this utility model is to provide a height-adjustable pole, which can meet the needs of most substation installation projects, shorten the construction period, greatly reduce the utilization rate of vehicles and the Occupancy of the construction road, its appearance is simple, easy to install (disassemble), easy to store, keep and transport, not limited by space and terrain conditions, not affected by problems such as whether there are wireless lines and equipment near the operating point, which greatly reduces the operating cost. The labor intensity of personnel ensures the safety of personal and equipment, and creates economic benefits, so it has strong practical promotion significance.

The utility model solves the technical problem and adopts the following technical solutions:

A height adjustable grill comprising:

A crossbeam, a square steel plate is arranged at one end of the crossbeam, and a suspension ring is arranged at the other end;

An upper column, the top of the upper column is provided with a flange capable of docking with the square steel plate;

A lower column, the bottom end of which is provided with a base steel plate;

Both the upper column and the lower column are provided with height adjustment holes, and the upper column and the lower column are butted and locked by a steel pin inserted into the height adjustment hole.

Structural features of the present utility model also are:

Both the upper column and the crossbeam are provided with connecting steel plates, and the two ends of the cable-stayed support are respectively connected to the connecting steel plates of the upper column and the connecting steel plates of the crossbeam.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

1. The utility model adopts a simple appearance and structure, and is easy to install and disassemble at the construction site, which solves the problems existing in the transportation and storage of the super-long wooden independent pole.

2. The utility model avoids the utilization rate of the crane and its occupancy of the construction road, and can flexibly change the hoisting location according to the needs, thus saving the cost of the vehicle and shortening the construction period.

3. The utility model effectively solves the space problem of the parking space and the safety distance of the boom swing required by the crane, ensures the safety of the construction, and avoids the need for adjacent intervals to be accompanied by power failures and even bus stop when the crane is hoisting. The disadvantages of operation have greatly reduced the economic losses caused by power outages and created economic and social benefits.

4. Since the utility model is not affected by problems such as indoor and outdoor space and terrain conditions, and is not affected by problems such as wireless lines and equipment near the operating point, it can meet the needs of most substation installation projects, so it has a wide range of applications. It has strong practical promotion significance.

Symbols in the figure: 1 beam, 11 square steel plate, 12 suspension ring, 2 upper column, 21 flange plate, 3 lower column, 31 base steel plate, 4 height adjustment hole, 5 steel pin, 6 cable-stayed support, 7 connecting steel plate.

The utility model will be further described below through specific embodiments in conjunction with the accompanying drawings.

Detailed ways:

Embodiment: Referring to Fig. 1-4, the height-adjustable grilling pole of this embodiment includes:

A crossbeam 1 is provided with a square steel plate 11 at one end of the crossbeam, and a suspension ring 12 is provided at the other end. The suspension ring is used to install a hoist. Docking and locking with bolts, the lower column 3 is docked with the upper column 2, and the bottom of the lower column is provided with a base steel plate 31 to prevent the pole from falling into the mud, and the base steel plate of the lower column can be used as a grounding terminal when there is induction electricity.

In order to realize the height adjustment, the upper column 2 and the lower column 3 are provided with a height adjustment hole 4, when the upper column and the lower column are butted, they are locked by the steel pin 5 inserted in the height adjustment hole.

In order to improve the load-bearing capacity and stability of the beam, connecting steel plates 7 are arranged on the upper column 2 and the beam 1, and the two ends of the cable-stayed support 6 are respectively connected to the connecting steel plates of the upper column and the connecting steel plates of the beam to form a triangular support .

Adopt the height-adjustable grilling pole operation method of the utility model, operate according to the following steps:

1. According to the size and height of the equipment to be installed, such as isolating switches and independent porcelain parts, adjust the height of the columns through the adjustment holes of the upper and lower columns and fix the steel pins, and assemble the columns and beams;

2. Assemble the cable-stayed support between the upper column and the beam to become a height-adjustable pole;

3. Stand up the pole and close to the equal-diameter pole or steel frame, and tie it firmly;

4. Install the hoist on the beam, and connect the grounding wire to the base steel plate of the lower column when there is induction electricity.

5. Carry out a comprehensive safety inspection on the grill;

6. Stop hoisting when the bottom of the lifting object is about 50-100mm from the ground, and check the pole again, then you can lift it and continue to complete the installation.

7. When dismantling, first remove the hoist, gently put down the pole, and disassemble according to the reverse steps of assembly.
