Description

Technical Field

[0001] The invention relates to a mobile device, in particular to a large-scale equipment lifting and moving device. Background Art

[0002] The chiller in a mine's refrigeration room was dismantled. The chiller had an overall dimension of 6109×2781×3594mm and a total weight of 27.8t. There was no lifting beam above the chiller on site and no fixed rooting point in front of the chiller, so it was impossible to use a hand winch to drag it. Therefore, it was extremely difficult to dismantle the chiller and move it out of the refrigeration room.

[0039] like Figure 5As shown, the first support 2 includes an L-shaped structure 21, the front end of the horizontal plate of the L-shaped structure 21 is wedge-shaped, which is convenient for insertion between the large equipment 6 and the track 1, and the rear end of the vertical plate of the L-shaped structure 21 has a first connecting support 22 for connecting the hydraulic cylinder 41. The first connecting support 22 is formed by two flat plates arranged at intervals, and the flat plates have connecting holes. The telescopic end of the hydraulic cylinder 41 is connected to the connecting hole through a pin shaft. The L-shaped structure 21 can be made of angle steel of at least 200*200.

[0040] like Figure 6 As shown, the second support 3 includes two vertical plates 31, a horizontal plate 32, and a second connecting support 33 for connecting the hydraulic cylinder 41. The two vertical plates 31 are made of steel plates of at least 30 mm, with length*width=220*260. The bottom of the vertical plates has a concave notch that is clamped on the track 1. The width of the concave notch is preferably adapted to the width of the track 1. The two vertical plates 31 are arranged in parallel and spaced apart. The horizontal plate 32 is connected between the two vertical plates 31. After the second support 3 is clamped on the track 1, the space between the horizontal plate 32 and the track 1 is used to place the jack 5.

[0042] Embodiment 2:

[0043] On the basis of the above-mentioned embodiment 1, the jack 5 described in this embodiment is an ultra-thin hydraulic split jack. In this embodiment, four jacks 5 are used to lift the equipment and fix the second support 3. The jack 5 has a stroke of at least 10t. The jack 5 can be selected as model: FPY-10, and is equipped with a hydraulic pump CP-180.

[0044] Of course, you can choose a larger stroke to save more time according to actual usage.

[0045] The large equipment moving method implemented by the large equipment lifting and moving device in the above-mentioned embodiment 1 or embodiment 2 comprises the following steps:

[0046] Step 1: Use at least four jacks 5 to be arranged at the four corners of the large equipment, lift the large equipment 6 to a height greater than the track 1, then arrange two tracks 1 under the large equipment 6, relieve the pressure on the jacks 5, and place the large equipment 6 on the track 1;

[0047] Step 2: Arrange the first support 2 and the second support 3 on the track 1 behind the large equipment 6, connect the hydraulic cylinder 41 between the first support 2 and the second support 3, and arrange the jack 5 between the cross plate 32 of the second support 3 and the track 1;

[0048] Step 3: operate the jack 5, the jack 5 is extended and supported on the bottom surface of the horizontal plate 32 and the top surface of the track 1, so that the second support 3 is fixed on the track 1, and the fixed position serves as the fulcrum of the hydraulic cylinder 41;

[0049] Step 4: operate the hydraulic cylinder 41, the hydraulic cylinder 41 extends, pushes the first support 2 forward, and then uses the hydraulic cylinder 41 to shift the large equipment 6 forward;

[0050] Step 5: When the hydraulic cylinder 41 reaches the maximum position and reaches the full stroke, the jack 15 and the hydraulic cylinder 41 are depressurized at the same time. During the depressurization, since the first support 2 is under the large equipment 6, the hydraulic cylinder 41 is extended and retracted, and the hydraulic cylinder 41 and the second support 3 are automatically moved forward at the same time;

[0051] Step 6: Press the jack 5 again to fix the second support 3 on the track 1, then press the hydraulic cylinder 41 to push the large equipment 6 forward again, and repeat the operation until the large equipment 6 is moved out.

[0052] In this embodiment, the second support 3 is fixed by the jack 5, and the extension of the hydraulic cylinder 41 pushes the first support 2, and then pushes the large equipment 6 to gradually move out along the track 1. This embodiment overcomes the problem of lifting equipment without a lifting point on site, and can still be used in a small space. It is an effective tool for moving heavy objects over a short distance and installing them in place. It has the advantages of large carrying capacity, good stability, and continuous movement. Therefore, it can be within a certain working range. Compared with the traditional method of using sleepers and rollers to transport heavy objects, it is safer, more labor-saving, time-saving, and cost-saving. It is simple to operate and only requires a small number of operators to use and operate. It can conveniently, quickly, safely, and accurately move heavy objects such as super-large equipment to the designated installation position.

[0053] At present, only 4-5 people are needed to operate it, and it can conveniently, quickly, safely and accurately move heavy objects such as chillers (weighing about 30 tons) and other super-large equipment to the designated installation location.

[0054] After the A Mine Refrigeration Room used the jacking and moving device to dismantle the chiller and achieved good results, the device was used again during the installation of the second phase chiller in the B Mine Refrigeration Room to quickly and conveniently move the new chiller into place on the foundation. It can be seen that the device can be used to achieve moving-in and moving-out operations. Since the device has a low cost and strong adaptability, it can be promoted to various occasions and is not limited to small spaces.

[0055] The moving method in this embodiment does not require the use of a large crane for cooperation during use, which saves machine hours, saves costs, greatly saves time, and is safe and efficient; it saves costs by about 50,000 yuan per time, which not only improves construction efficiency, but also reduces construction costs, achieving the purpose of reducing costs and increasing efficiency.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
