DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides an implementation scheme: in the application process of modern hot injection furnaces, the heavy top cover of the hot injection furnace needs to be lifted and lowered by a hydraulic device when it is opened and closed. At present, the lifting of the hot injection furnace mainly adopts a unilaterally controlled hydraulic lifting device. However, since this structure only bears force on one side, it often causes the guide rail on the corresponding side to be severely worn, resulting in the top cover not opening and closing fully or causing problems such as jamming.

[0022] In view of the above problems, the present application discloses a novel hydraulic lifting device for hot injection furnace, the lifting device is divided into a furnace body 1 and a furnace cover 2, the furnace cover 2 is buckled on the upper part of the furnace body 1, the top of the furnace body 1 is sealed by the furnace cover 2, the furnace cover 2 is integrated with a feeding port and other structures, at least one pair of guide seats 3 are arranged on both sides of the furnace body 1, a pair of guide seats 3 are equipped with a pair of guide rods 4, the pair of guide rods 4 are used in conjunction with the pair of guide seats 3, the pair of guide rods 4 are connected to both sides of the furnace cover 2, the pair of guide seats 3 guide the pair of guide rods 4, a lifting adjustment seat 5 is arranged on the furnace body 1, and the lifting adjustment of the pair of guide seats 3 and the pair of guide rods 4 is synchronously controlled by the lifting adjustment seat 5;

[0023] Therefore, the lifting adjustment seat 5 is located between the pair of guide seats 3, and a synchronous lifting structure is provided on the lifting adjustment seat 5 and connected to the pair of guide seats 3, and the lifting adjustment seat 5 can provide control power for the synchronous lifting of the pair of guide rods 4;

[0024] Specifically, a pair of guide grooves are arranged on a pair of guide seats 3, and the pair of guide grooves and a pair of guide rods 4 constitute a pair of hydraulic lifting devices. The pair of guide grooves cooperate with the pair of guide rods 4, and hydraulic oil is pumped into the pair of guide grooves through a pair of hydraulic transmission pipes 12. In addition, a pair of guide pistons 6 are arranged at the bottom ends of the pair of guide rods 4. The guide pistons 6 are lifted and slid in the pair of guide grooves through hydraulic action, thereby realizing the lifting and lowering adjustment of the corresponding pair of guide rods 4, and then realizing the lifting and lowering switch of the furnace cover 2.

[0025] According to the instruction manual Figure 1-3It can be seen that the synchronous lifting structure includes a hydraulic storage bin 7, a hydraulic storage bin 7 is provided on the lifting adjustment seat 5, a screw pair 8 and a control screw 9 are provided on the top of the hydraulic storage bin 7, the screw pair 8 is provided with a control motor 10 through a gear set linkage, and a control piston 11 is connected to the end of the control screw 9, and the control piston 11 cooperates with the inner cavity of the hydraulic storage bin 7, and the hydraulic storage bin 7 is connected with a pair of hydraulic transmission pipes 12;

[0026] During the specific implementation process, the control motor 10 drives the gear group to rotate in conjunction with the screw pair, so that the screw pair is engaged with the control screw 9, and then the control screw 9 drives the control piston 11 to move up and down, so that the control piston 11 changes the pressure in the hydraulic storage bin 7, and pushes out or withdraws the hydraulic oil. Since a pair of hydraulic transmission pipes 12 are symmetrically connected to the hydraulic storage bin 7, under the pushing action of the control piston 11, the hydraulic oil is pushed into the hydraulic transmission pipe 12 by pushing the uniform diversion and then passes through to the guide groove, pushing the guide rod 4 to move and lift the furnace cover 2. During the lowering process of the furnace cover 2, with the upward movement of the control screw 9 and the control piston 11, the hydraulic oil is caused to flow back through the hydraulic transmission pipe 12 under the heavy pressure of the furnace cover 2 and enter the inner cavity of the hydraulic storage bin 7.

[0027] As a preferred solution, further, the lifting and adjusting seat 5 is separately connected to the outer peripheral wall of the furnace body 1 through a supporting stand, which is convenient for removal and replacement.

[0028] As a preferred solution, further, the top ends of a pair of guide rods 4 are connected to the two sides of the furnace cover 2 through a pair of fixing parts, a pair of auxiliary rods 13 are arranged on both sides of the guide rods 4, and a pair of auxiliary grooves are arranged on the guide seat 3 to match the pair of auxiliary rods 13.

The control piston 11 and the inner cavity of the hydraulic storage bin 7 adopt special-shaped limiters. In the specific implementation process, the rotating seat 14 on the lifting and adjusting seat 5 and the screw pair are movably installed, which plays a role in limiting the installation of the screw pair.

[0030] As a preferred solution, further, at least one pair of control valves 15 are provided on the pair of hydraulic transmission pipes 12 to facilitate the control of the switching of the hydraulic transmission pipes 12 .

[0031] As a preferred solution, further, a pair of pipe joints 16 are provided on the lifting and adjusting seat 5 to be connected to the ends of a pair of hydraulic transmission pipes 12, so as to facilitate the removal and replacement of the hydraulic transmission pipes 12 for maintenance.

[0032] From the above, it can be generally known that the new hydraulic lifting device of the hot injection furnace adopts a hydraulic lifting device symmetrical on both sides to lift the furnace cover 2, and uses an auxiliary telescopic rod structure to assist in stabilizing the lifting and lowering of the furnace cover 2, and then the control piston 11 controlled by the screw lifting controls the hydraulic oil to the guide rod 4 through the hydraulic transmission pipe 12, so that the hydraulic lifting devices on both sides of the hot injection furnace work synchronously and the furnace cover 2 is lifted or lowered synchronously.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
