Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance auxiliary equipment, and in particular relates to a maintenance and transfer device for equipment with limited space. Background Art

[0002] There are many equipment in the oil depot's oil delivery area, tank pump room, oil and gas recovery area, etc. For example, there are at least 50 to 60 oil pumps in an oil depot, and as many as hundreds of them. In refineries and chemical companies, there are thousands of them. There are many difficulties in the daily maintenance of such equipment, including: (1) There are many equipment with different specifications and models, and there are no special maintenance auxiliary tools; (2) The equipment is frequently used and is prone to oil leakage, requiring regular disassembly and maintenance; (3) The equipment is heavy, with the heaviest weighing about 1 ton, making it difficult for personnel to carry it; (4) There are many equipment connected to the pipeline, and the gaps between adjacent equipment are relatively small in design to avoid oil leakage, save energy, and reduce energy transmission loss, resulting in limited maintenance space. Personnel are easily squeezed and injured by adjacent equipment during maintenance; (5) When one equipment needs to be repaired, for safety reasons, the adjacent running equipment must be stopped, affecting the oil depot's operation plan; (6) The installation site of the oil depot equipment is mostly in an explosion-proof hazardous area. Ordinary large hoists or forklifts are not explosion-proof, and hand hoists used to build a scaffold are even more unsafe. Every time maintenance and disassembly occurs, non-explosion-proof equipment and tools are used, posing a serious risk. Some equipment is less than 30cm apart, leaving no room for maintenance.

[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] The utility model provides a maintenance and transfer device for equipment with limited space. Figure 1 , including a base 1, a water tank 2 is fixed on one side of the base, and a hydraulic hanger 3 is fixed on the other side.

[0032] A telescopic mechanism 4 is provided on the side of the base for receiving equipment with limited space to be repaired that is lifted by a hydraulic hanger.

[0033] In the present invention, a liquid level gauge 5 is provided on the outside of the water tank 2. Based on the weight of the space-constrained equipment to be repaired, water is filled in the water tank 2 to the corresponding scale, so that the space-constrained equipment to be repaired can be moved out of the confined space and placed on the telescopic mechanism 4, thereby maintaining the weight balance on both sides of the entire transfer device.

[0034] In the present invention, the plane of the base 1 is made of Q345B steel plate, and the side is welded with 14#b channel steel. The base size is 1500 mm long and 800 mm wide.

[0035] In the present invention, the telescopic mechanism 4 is realized by using different types of channel steels, specifically:

[0036] Align the U-shaped opening of the 14#b channel steel with the outer side of the long side of the base 1 and weld them to form an empty groove on the outer side of the two long sides of the base 1; insert the 10# channel steel into the empty groove with the U-shaped opening facing downward to enable the 10# channel steel to freely expand and contract in the empty groove, thereby forming a telescopic mechanism.

[0037] Furthermore, an I-shaped steel plate 7 with two ends bent downward is designed. When the telescopic mechanism needs to accommodate equipment with limited space to be repaired, an appropriate number of I-shaped steel plates 7 are selected according to the diameter of the equipment with limited space to be repaired, and are clamped on the two protruding channel steels and tightened. The equipment with limited space to be repaired is placed on the I-shaped steel plate to play a supporting role.

[0038] In the present invention, the water tank 2 is welded with Q345B steel plates, and the dimensions of the water tank are: 900 mm high, 800 mm wide, and 920 mm long.

[0039] Furthermore, an openable and closable cover is welded to the water tank 2 via hinges.

[0040] Furthermore, a handle is welded on the water tank 2 .

[0041] In the present invention, the liquid level gauge 5 adopts a magnetic flap liquid level gauge, normal temperature type, 304 stainless steel, 25 mm in diameter, and a measuring range of 800 mm. The installation method of the liquid level gauge is:

[0042] Weld the bent C-shaped piece 8 to one side of the box 100 mm from the top. Open a 27 mm diameter circular hole on the right side of the same side of the box where the C-shaped piece 8 is welded, near the bottom plate. Insert a 25 mm diameter, 30 mm long, welded hot-dip galvanized steel pipe with an outer thread vertically into the hole no more than 5 mm away. Use a multi-purpose angle ruler to measure that the inserted pipe is at a 90° right angle to the joint surface. Then spot weld the joint seam. Measure the verticality again with a multi-purpose angle ruler. After calibration, fully weld the joint gap. Then wrap the welded steel pipe external thread evenly with no less than 10 layers of raw tape, put the 25 mm diameter hot-dip galvanized steel internal thread elbow on the welded steel pipe external thread, tighten clockwise, and at the same time ensure that the other bend of the internal thread elbow is vertically upward, wrap the 25 mm diameter ball valve external thread evenly with no less than 10 layers of raw tape, put the ball valve external thread on the internal thread upward bend, tighten clockwise, fix the 25 mm diameter thread at the bottom of the magnetic flap level gauge to the ball valve with a connecting nut, and use a 200 mm clamp to fix the upper part of the magnetic flap level gauge 5 to the C-shaped part 8.

[0043] In the present invention, universal iron casters 6 are provided at the four corners of the base 1, which can realize moving the space-constrained equipment to be repaired out of the space-constrained area, pushing the entire set of equipment away from the site, and transporting it to a safe operating area for professional maintenance.

[0044] In the present invention, the hydraulic hanger 3 adopts an adjustable boom rod and a maximum lifting capacity of 3 tons. The main support column of the hydraulic hanger is welded on the base at a certain distance from the water tank. The welding points of the two auxiliary support columns and the welding points of the main support column form an equilateral triangle.

[0045] Based on the above-mentioned space-constrained equipment maintenance and transfer device, its specific operation process is as follows:

[0046] (1) Check the weight of the space-restricted equipment to be repaired;

[0047] (2) According to the weight of the equipment, find the corresponding "water height-weight" scale line on the water tank level gauge of the space-constrained equipment maintenance and transfer device, and add water to the water tank to the required scale line to maintain the weight balance on both sides of the entire transfer device; this method does not require the water tank to be filled every time, which wastes water and is inconvenient to push;

[0048] (3) Remove the connecting bolts of the space-restricted equipment to be repaired;

[0049] (4) Use the hydraulic hook of the space-restricted equipment maintenance and transfer device to lift the space-restricted equipment to be repaired. After moving out of the space-restricted area, pull out two 10# channel steels from the 14#b-type channel steel and align them with the hoisted object. Select 1-3 rectangular steel plates according to the base diameter of the hoisted equipment and clamp them on the pulled-out channel steels. Tighten the two ends of the channel steels clockwise with T-shaped handles. Slowly lower the hydraulic rod to let the hoisted equipment fall in the center of the clamping steel plate. Keep the lifting rope in a vertically stretched state to ensure the safety and stability of the equipment during pushing. The entire set of equipment can be pushed away from the site and transported to a safe operating area for professional maintenance.

[0050] The space-limited equipment maintenance and transfer device provided by the utility model is ingeniously simple in design, scientifically reasonable, and easy to operate. The initial investment is less than 10,000 yuan, the device is highly practical, and can be repeatedly used in the maintenance process of equipment of different weight classes.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
