Description

A miniature movable support tray

technical field

The utility model relates to an auxiliary tool for mechanical maintenance, in particular to a miniature movable supporting tray for maintenance operation in a large equipment (in a limited space).

Background technique

At present, in the production process of polyvinyl chloride, it is difficult for most equipment to enter the confined space for inspection and maintenance, and the risk factor is high, which can only be overcome by safety belts and other protective measures; When replacing the discus with the slag valve, difficulty 1 requires a small maintenance space; difficulty 2 replaces spare parts that are heavy, and it is extremely difficult to use manpower to lift them up. Since there is no effective solution, the difficulty can only be overcome with human maintenance tools.

Utility model content

The purpose of the utility model is to provide a miniature movable support tray, which solves the difficult and dangerous status quo of maintenance operations in large-scale equipment (confined space), and is suitable for maintenance operations in large-scale equipment (confined space) in enterprises.

The purpose of this utility model is achieved through the following technical solutions.

A miniature movable support tray, including a base, a support device arranged on the base in an inclined distribution, and a link bracket; one end of the support device is connected to the base through a tray connecting shaft, and the other end is supported by an adjustable screw rod; A tray is arranged on the supporting device, and a connecting rod is arranged on the tray, and the connecting rod is connected with the connecting rod bracket.

Preferably, tray pulleys are provided on the tray.

Preferably, the connecting rod bracket is respectively provided with a sliding guide rail and a main screw rod.

Preferably, the connecting rod is provided with a connecting rod fixing pin.

Preferably, a base push handle is provided at the front end of the base.

Compared with the prior art, the utility model has the beneficial effects that the design and processing structure is simple, the raw material is the most commonly used steel material, and the utility model is easy to use and easy to understand. After the device is put into use, on the one hand, the efficiency of equipment maintenance is greatly improved, and the loss of manpower and material resources is reduced; on the other hand, the safety factor of maintenance operations is guaranteed.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Fig. 1 in conjunction with Fig. 2 and Fig. 3, the miniature movable support tray includes a base 5, and a support device and a connecting rod bracket arranged on the base 5 in an inclined distribution; one end of the support device connects the shaft 7 with the tray The base 5 is connected, and the other end is supported by an adjustable screw rod 3; a tray 6 is provided on the supporting device, and a connecting rod 8 is arranged on the tray 6, and the connecting rod 8 is connected with the connecting rod bracket, and the connecting rod 8 is provided with a connecting rod for fixing Pin 9. A sliding guide rail 2 and a main screw rod 1 are respectively arranged on the connecting rod bracket. Four tray pulleys 10 are arranged on the tray 6 to connect with the supporting device. Wherein, a base push handle 4 is also provided at the front end of the base 5 .

According to the principle of combined use of levers and multi-links, the utility model uses a common trolley as the chassis (to realize the movable type), and designs a support device with a certain angle on the surface of the chassis. One end is connected with the chassis by a "shaft", and the other One end is fixed on the base with a double screw rod and connected with the "U" type double nut holes of the support device (the angle of the support device can be adjusted), a tray (with four pulleys) is designed above the support device, and the support device is connected by a connecting rod. Connect with the tray device to realize the transformation of the tray in the three-dimensional space angle to achieve the exact position required. Its three-dimensional structure is shown in Figure 4. The materials selected for this design are common, and the manufacturing process is simple. Common steel plates and angle steels with a thickness of 2mm are used as the main material skeleton of the design. When in use, only the maintenance personnel are required to operate outside the equipment, place the "support car" in the position of the parts to be disassembled and installed in the equipment, and adjust the relative position of the connecting rod, the main screw rod and the double screw rod with a wrench, and it can be easily disassembled. Install equipment.

The above content is a further detailed description of the utility model in conjunction with specific preferred embodiments. It cannot be determined that the specific embodiment of the utility model is limited to this. Under the premise of the new concept, some simple deduction or replacement can also be made, which should be regarded as belonging to the utility model and the patent protection scope is determined by the submitted claims.
