[0002] An industrial boiler heat pump is a device that can utilize the heat energy in low-temperature heat sources (such as air, water, soil, etc.) and convert it into high-temperature heat energy through heat pump technology. It is used in industrial heating, drying, refrigeration and other processes. During the installation process of the industrial boiler heat pump, it is necessary to use an industrial boiler heat pump lifting device to lift the heat pump so that the staff can move and transport the heat pump to the designated installation location.

[0003] After searching, the Chinese patent application No. 201920368601.6 discloses a bucket elevator for handling equipment, including an elevator frame body, winding rollers are fixedly installed on both sides of the rotating shaft, chains are wound on the two winding rollers, a motor is fixedly installed on the back of the top of the elevator frame body, and two supporting columns in the middle of the elevator frame body are movably connected with moving columns, and a bottom plate is fixedly installed on the outside of the two moving columns, and guardrails are fixedly installed on both sides of the top of the bottom plate. Electric telescopic rods are fixedly installed on the inner sides of the bottom ends of the two guardrails, and one end of the two electric telescopic rods is fixedly installed with a limited card seat, and a baffle is movably connected to the front of the bottom plate. The utility model is a bucket elevator for handling equipment. The electric telescopic rod drives the limited card seat to move, and the distance between the two limited card seats is adjusted, which is convenient for fixing mechanical equipment of different sizes. By setting a reversible baffle, it is convenient for loading and unloading mechanical equipment, saving time and effort;

[0004] The above patent still has the following shortcomings: (1) It is not convenient to move the heat pump. Since the device is usually fixed directly on the ground by a base, it is not convenient to move and transport the device. If universal wheels are installed at the bottom of the device, the stability of the device will be reduced, causing the device to move, shake and fall during the lifting process, thereby reducing the safety of the device;

[0005] (2) It is inconvenient to load and unload the heat pump. Due to its large size and high weight, the heat pump is not convenient to load and unload on the top of the discharge tray.

[0006] Therefore, an industrial boiler heat pump lifting device is urgently needed to solve the above problems. Utility Model Content

[0023] Through the above technical solution, the roller rolls inside the discharge tray, so that the heat pump can be easily moved on the top of the discharge tray, and the electric telescopic rod is started to shrink and lock the fixed position of the roller.

[0024] As a preferred technical solution of the present application, the rollers are arranged in a plurality of groups inside the discharge tray, and the plurality of groups of rollers are distributed at equal intervals inside the discharge tray.

[0029] The roller rolls inside the discharge tray, so that the heat pump can be easily moved on the top of the discharge tray. The electric telescopic rod is started to shrink and lock the fixed roller to fix its position, thereby realizing the easy loading and unloading function of the device, facilitating the loading and unloading of the heat pump placed on the surface of the discharge tray, reducing the manpower consumed in loading and unloading the heat pump, and improving the installation efficiency of the heat pump.

[0040] The material conveying structure 8 is arranged on the top of the material discharging tray 12 and is used to move the heat pump;

[0041] The bottom plate 10 is fixed to the bottom end of the support frame 1;

[0042] The transport structure 9 is arranged on both sides of the top of the base plate 10, wherein the transport structure 9 includes a fixed frame 901 fixed on both sides of the top of the base plate 10, a transmission assembly installed at the top inside the fixed frame 901, a movable plate 906 installed at the bottom end of the transmission assembly, a sliding rod 905 inserted inside the movable plate 906 and connected to the base plate 10, and universal wheels 904 installed on both sides of the bottom end of the movable plate 906.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the transmission assembly includes a bidirectional screw 903 inserted in the top of the fixed frame 901, a stepper motor 908 installed on one side of the fixed frame 901 and connected to the bidirectional screw 903 at the rotating end, a moving block 902 threadedly connected to the outside of the bidirectional screw 903, and a push arm 907 rotatably connected to the bottom of the moving block 902 and forming a rotating structure with the moving plate 906. The directions of the external threads at both ends of the bidirectional screw 903 are opposite, the moving blocks 902 are symmetrically distributed on the vertical center line of the fixed frame 901, and a sliding structure is formed between the slide rod 905 and the moving plate 906.

The movement of the moving plate 906 is guided by the sliding of the moving plate 906 on the outer side of the slide rod 905;

[0047] By rolling the roller 807 inside the discharge tray 12, the heat pump can be easily moved on the top of the discharge tray 12, so that the staff can carry the heat pump to the top of the discharge tray 12. In the process of lifting the heat pump, the electric telescopic rod 801 is started to contract, so that the electric telescopic rod 801 pulls the fixed plate 802 to move upward, and then the fixed plate 802 drives the limit block 805 to get into the gap of the gear 806 to fix the position of the gear 806, thereby fixing the position of the roller 807, making it difficult for the roller 807 to roll during the lifting process to prevent the heat pump from falling. The guide rod 804 reduces the shaking of the electric telescopic rod 801, and the compression spring 803 facilitates the separation of the limit block 805 and the gear 806.
