Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary installation structures for industrial refrigeration equipment, and in particular to a suspension frame for hoisting industrial refrigeration equipment. Background Technology

[0002] During the installation, maintenance, and replacement of large industrial refrigeration equipment, it is often necessary to hoist it to a specific height and position. Traditional methods mainly rely on large cranes or simple hoisting equipment for overall lifting. However, such equipment is often huge and heavy, and the installation space is limited with high precision requirements. It is difficult to achieve precise horizontal displacement, vertical height, and angle fine-tuning by crane alone. It often requires multiple people to manually pry or repeatedly lift and lower, which is not only inefficient and labor-intensive, but also poses significant safety risks such as equipment collision damage and personnel crushing and falling. Some existing simple suspension frames also generally lack stable and convenient multi-dimensional fine-tuning functions, which cannot meet the stringent requirements of safe, efficient, and precise positioning of large refrigeration equipment in narrow or complex spaces. Therefore, there is an urgent need for a special, stable suspension frame with fine adjustment capabilities to solve the above problems.

[0003] A search revealed Chinese Patent Publication No. CN220601156U, which relates to the field of auxiliary installation structures for industrial refrigeration equipment, and particularly to a hoisting suspension frame for industrial refrigeration equipment. This frame includes a suspension mechanism comprising a telescopic rod, one end of which is connected to the building's roof, and the other end to the industrial refrigeration equipment. The telescopic rod's extension and retraction can raise and lower the industrial refrigeration equipment. This application facilitates maintenance of the industrial refrigeration equipment by workers; however, this solution still suffers from problems such as poor lifting accuracy, lack of horizontal adjustment, and absence of safety protection. Utility Model Content

[0004] The purpose of this utility model is to provide a suspension frame for hoisting industrial refrigeration equipment, in order to solve the problems of poor lifting accuracy, lack of horizontal adjustment, and lack of safety protection in existing solutions.

[0005] To achieve the above objectives, an industrial refrigeration equipment hoisting suspension frame is provided, including a crossbeam, a sliding rod fixedly connected to one side of the crossbeam, a screw threadedly connected to the other side of the crossbeam, a motor fixedly connected to the inner side of the left end of the crossbeam, and the output shaft of the motor being fixedly connected to the screw via a coupling;

[0006] Each side of the screw is connected to a lifting rod top plate, and the lifting rod top plate is fixedly connected to the slide rod.

[0007] According to the aforementioned industrial refrigeration equipment hoisting suspension frame, a limit rod is fixedly connected between the top plates of the lifting rod.

[0008] According to the aforementioned industrial refrigeration equipment hoisting suspension frame, two lifting rods are fixedly connected to the bottom surface of the top plate of the lifting rod, and a lifting rod base is fixedly connected to the end of the lifting rod.

[0009] According to the aforementioned industrial refrigeration equipment hoisting suspension frame, a locking plate is fixedly connected to the bottom surface of the lifting rod base, a lifting platform is fixedly connected to the bottom surface of the locking plate, and a fixing bolt is fitted onto the locking plate.

[0010] According to the aforementioned industrial refrigeration equipment hoisting suspension frame, the two ends of the crossbeam are fixedly connected to brackets, the bottom end of the bracket is fixedly connected to a bracket base plate, and a bracket fixing plate is fixedly connected between the bracket and the bracket base plate.

[0011] According to the aforementioned industrial refrigeration equipment hoisting suspension frame, the frame has a support groove inside, a reinforcing rib is fixedly connected inside the support groove, and two reinforcing rib fixing plates are fixedly connected to the frame.

[0012] According to the aforementioned industrial refrigeration equipment hoisting suspension frame, the bottom surface of the frame is fixedly connected with four casters.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. This suspension frame overcomes the bottleneck of traditional hoisting equipment, which cannot simultaneously achieve precise height and horizontal position adjustment, through the rigid linkage between the motor-driven screw and the slide rod: the rotation of the screw pushes the top plate of the lifting rod to rise and fall vertically along the slide rod, completely solving the problem of installation failure caused by height deviation between industrial refrigeration equipment and foundation bolt holes; after the equipment is fixed to the lifting platform by the locking plate, the position can be adjusted laterally as a whole to avoid pipe or wall obstacles, which improves efficiency compared to the traditional operation method that requires disassembly and re-hanging, and is especially critical in narrow machine rooms.

[0015] 2. This suspension frame innovatively integrates a composite reinforced support and a dual-mode mobile locking system to achieve full-dimensional stability during the hoisting process: the reinforcing ribs in the grooves of the support, together with the double-reinforced fixing plates, ensure that there is no risk of tipping over when the equipment is raised or lowered; the casters support flexible movement, and after positioning, the base plate of the support is in full contact with the ground to distribute pressure, and the mechanical locking is completed by fixing bolts, which greatly reduces the safety hazards of high-altitude operations.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model provides an industrial refrigeration equipment hoisting suspension frame, which includes a crossbeam 5, a slide rod 14 fixedly connected to one side of the crossbeam 5, a screw rod 15 threadedly connected to the other side of the crossbeam 5, a motor 16 fixedly connected to the inner side of the left end of the crossbeam 5, and the output shaft of the motor 16 fixedly connected to the screw rod 15 through a coupling.

[0026] Each side of the screw 15 is connected to a lifting rod top plate 18, which is fixedly connected to the slide rod 14. The motor 16 inside the crossbeam 5 starts and drives the screw 15 to rotate through a coupling. The threads on both sides of the screw 15 engage with the two lifting rod top plates 18 respectively, converting the rotational motion of the screw 15 into synchronous, opposite linear motion of the two lifting rod top plates 18 along the fixed slide rod 14.

[0027] A limiting rod 17 is fixedly connected between the top plates 18 of the lifting rods. The limiting rod 17 effectively constrains the relative position of the two top plates 18 of the lifting rods, preventing them from twisting relative to each other during movement and ensuring strict synchronization of movement on both sides.

[0028] Two lifting rods 11 are fixedly connected to the bottom surface of the lifting rod top plate 18. The lifting rod base 12 is fixedly connected to the end of the lifting rod 11. The lifting rod top plate 18 drives the lifting rod base 12 to move vertically through the four lifting rods 11. The lifting platform 9 at its end carries the equipment to achieve precise lifting.

[0029] A locking plate 13 is fixedly connected to the bottom surface of the lifting rod base 12, and a lifting platform 9 is fixedly connected to the bottom surface of the locking plate 13. A fixing bolt 10 is connected to the locking plate 13. After the equipment is in place, the pre-made bolt holes of the locking plate 13 are rigidly connected to the equipment base through the fixing bolt 10, thus eliminating the common risk of settlement of hydraulic locks.

[0030] The two ends of the crossbeam 5 are fixedly connected to the bracket 1, the bottom end of the bracket 1 is fixedly connected to the bracket base plate 7, and the bracket fixing plate 6 is fixedly connected between the bracket 1 and the bracket base plate 7. The bracket 1 and the bracket fixing plate 6 are welded to form a portal frame, which together constitutes a stable and reliable main support frame.

[0031] The bracket 1 has a bracket groove 4 inside, and a reinforcing rib 3 is fixedly connected inside the bracket groove 4. Two reinforcing rib fixing plates 2 are fixedly connected to the bracket 1. The radial reinforcing ribs 3 embedded in the bracket groove 4 are anchored by the fixing plates 2, which converts the lateral impact force into axial compressive stress.

[0032] The bottom of the bracket 1 is fixedly connected with four casters 8, which gives the entire suspension bracket flexible movement capability and makes it easy to adjust to the required position in the working area.

[0033] Working principle: During use, the operator turns on the motor 16, which drives the screw 15 to rotate within the crossbeam 5 via the coupling. Due to the symmetrical threaded engagement between the screw 15 and the threads of the two lifting rod top plates 18, the rotational motion is converted into the synchronous reverse linear motion of the lifting rod top plates 18 along the slide rod 14. The lifting rod top plates 18 drive the lifting rod base 12 and the lifting platform 9 to rise and fall vertically via the lifting rod 11 at the bottom. After the lifting is completed, the locking plate 13 is locked to the equipment by the fixing bolts 10 to prevent displacement. The entire system is supported by the bracket 1, whose internal reinforcing ribs 3 and bracket fixing plate 6 enhance rigidity. The universal wheels 8 at the bottom facilitate movement and positioning, while the limiting rod 17 constrains the relative position of the lifting rod top plates 18, ensuring the synchronous movement of the dual lifting mechanism and its resistance to eccentric loads. Overall, this system is conducive to achieving millimeter-level height precision positioning of industrial refrigeration equipment through a bidirectional screw and slide rod precision lifting system, improving installation efficiency. Combined with the composite reinforced bracket structure, it ensures safe operation with zero swaying and zero overturning under high loads, completely solving the positioning deviation and instability risks of traditional hoisting.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
