[0003] A search revealed that CN213748066U discloses a heat exchanger tube hoisting structure for waste heat recovery equipment. This hoisting structure includes multiple sets of heat exchanger tube water circuit assemblies. Each water circuit assembly includes spiral finned tubes and elbows, as well as two parallel hanging plates. Each hanging plate has a row of equidistant finned tube receiving slots on both its front and rear sides, with the front and rear rows of slots staggered. Pipe clamps are installed at the outer ends of the finned tube receiving slots, which cooperate with the slots to fix the water circuit assembly. Water circuit assemblies are installed at the front and rear of the hanging plates. Each set of water circuit assemblies consists of multiple vertically arranged parallel water pipes. The two ends of each water pipe are embedded in the finned tube receiving slots on the same side of the two hanging plates. The outer ends of adjacent upper and lower water pipes are connected by elbows to form a serpentine water circuit assembly. The elbows are located on the outer sides of the two hanging plates, and the parallel water pipes are located between the two hanging plates. This structure saves manufacturing costs and is convenient for manufacturing and installation.

[0004] However, the above-mentioned heat exchanger tube hoisting structure for waste heat recovery equipment still has the following problems: the above-mentioned heat exchanger tube hoisting structure for waste heat recovery equipment uses pipe clamps at the outer end of the plate tube receiving groove, and the water circuit assembly is fixed by the pipe clamps in conjunction with the plate tube receiving groove. When the heat exchanger tube water circuit assembly is installed in the plate tube receiving grooves on both sides, it is necessary to manually fix the pipes one by one with multiple pipe clamps, which results in low installation efficiency. Utility Model Content

[0005] This utility model proposes a heat exchange tube hoisting structure for waste heat recovery equipment, which solves the problem of low installation efficiency caused by tube clamp fixation in the prior art.

[0006] The technical solution of this utility model is as follows: A heat exchanger tube hoisting structure for waste heat recovery equipment includes two sets of heat exchanger tube assemblies arranged vertically and vertically, and two hoisting plates for hoisting the two sets of heat exchanger tube assemblies. One side of the hoisting plate is provided with a first receiving groove for accommodating one set of heat exchanger tube assemblies, and the other side of the hoisting plate is provided with a second receiving groove for accommodating the other set of heat exchanger tube assemblies. The tail of the second receiving groove is provided with a hook groove. The hoisting plate is provided with a clamping component between the first receiving groove and the second receiving groove for securing the two sets of heat exchanger tube assemblies in the first receiving groove and the hook groove. The outer side of the hoisting plate is fixed with a positioning rod for positioning the clamping component so that the heat exchanger tube assembly can be inserted into the first receiving groove or the second receiving groove.

[0007] Preferably, the openings of the first receiving groove and the second receiving groove are both inclined upwards, and are arranged alternately at the top and bottom.

[0008] Preferably, the hook groove of the second receiving groove is inclined in the same direction as the first receiving groove, and the remaining part of the second receiving groove is inclined in the opposite direction to the first receiving groove.

[0009] Preferably, the clamping component includes a hook, which is shaped like a seahorse with hooks at both ends, and is rotatably connected to the hanging plate via a pivot at its center. The pivot is fitted with a torsion spring that elastically connects the hook to the hanging plate.

[0010] Preferably, the hook tends to rotate toward the positioning rod under the elastic force of the torsion spring.

[0011] Preferably, the heat exchange pipeline assembly includes several horizontally arranged horizontal pipes and bends that connect the horizontal pipes in a serpentine manner.

[0012] The beneficial effects of this utility model are as follows: 1. The hook groove structure design of the second receiving groove in this utility model, compared with the prior art, enables the clamping component to tighten the two sets of heat exchange pipeline assemblies together, preventing the horizontal pipe in the lower position from sliding in the second receiving groove and affecting the fixing effect. 2. In this utility model, when installing two sets of heat exchange pipe assemblies, the horizontal pipes can be pressed inwards to squeeze the wedge-shaped surface of the hooks, thereby opening the hooks and allowing the horizontal pipes of the two sets of heat exchange pipe assemblies to slide smoothly into the tail of the first receiving groove and the hook groove at the tail of the second receiving groove. When released, each hook can automatically lock each horizontal pipe in the first receiving groove and the hook groove through the torque of the torsion spring. Compared with the prior art, this utility model can realize the automatic positioning of the two sets of heat exchange pipe assemblies, thereby improving the hoisting efficiency.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a heat exchanger tube hoisting structure for waste heat recovery equipment, including two sets of heat exchanger tube assemblies 1 arranged vertically and vertically, and two hoisting plates 2 for hoisting the two sets of heat exchanger tube assemblies 1. One side of the hoisting plate 2 is provided with a first receiving groove 21 for accommodating one set of heat exchanger tube assemblies 1, and the other side of the hoisting plate 2 is provided with a second receiving groove 22 for accommodating the other set of heat exchanger tube assemblies 1. The tail of the second receiving groove 22 is provided with a hook groove 221. The hoisting plate 2 is provided with a clamping component 3 between the first receiving groove 21 and the second receiving groove 22 for securing the two sets of heat exchanger tube assemblies 1 in the first receiving groove 21 and the hook groove 221. The outer side of the hoisting plate 2 is fixed with a positioning rod 4 for positioning the clamping component 3 so that the heat exchanger tube assembly 1 can be inserted into the first receiving groove 21 or the second receiving groove 22.

[0017] Please see Figure 2 and Figure 3 The openings of the first receiving groove 21 and the second receiving groove 22 are both inclined upwards and are alternately arranged to maintain the structural strength of the hanging plate 2. The hook groove 221 of the second receiving groove 22 is in the same direction of inclination as the first receiving groove 21, while the remaining parts of the second receiving groove 22 are in the opposite direction of inclination to the first receiving groove 21. Compared with the prior art, the hook groove 221 structure design of the second receiving groove 22 can make the clamping component 3 tighten the two sets of heat exchange pipe assemblies 1 together, preventing the horizontal pipe 11 in the lower position from sliding in the second receiving groove 22 and affecting the fixing effect.

[0018] Please see Figure 3 and Figure 4The clamping component 3 includes a hook 31, which is seahorse-shaped with hooks at both ends. Its center is rotatably connected to the hanging plate 2 via a pivot 32. A torsion spring 33 is fitted over the pivot 32 to elastically connect the hook 31 to the hanging plate 2. The end of the hook 31 has a wedge-shaped surface. Under the elastic force of the torsion spring 33, the hook 31 tends to rotate towards the positioning rod 4. Initially, the hook 31 abuts against the positioning rod 4 under the elastic force of the torsion spring 33. The surface is exactly located within the first receiving groove 21 and the second receiving groove 22. By pressing inward, the horizontal tube 11 squeezes the wedge-shaped surface of the hook 31, thereby opening the hook 31. This allows the horizontal tubes 11 of the two sets of heat exchange pipe assemblies 1 to slide smoothly into the tail of the first receiving groove 21 and the hook groove 221 at the tail of the second receiving groove 22. When released, each hook 31 can automatically lock each horizontal tube 11 into the first receiving groove 21 and the hook groove 221 by the torque of the torsion spring 33.

[0019] Furthermore, the heat exchange pipeline assembly 1 includes several horizontally arranged horizontal pipes 11 and bends 12 that connect the horizontal pipes 11 in a serpentine manner. The two sets of heat exchange pipeline assemblies 1 can be assembled in advance. After assembly, each horizontal pipe 11 of one set of heat exchange pipeline assemblies 1 is placed into the first receiving groove 21 on one side of the hanging plate 2, and each horizontal pipe 11 of the other set of heat exchange pipeline assemblies 1 is placed into the second receiving groove 22 on the other side of the hanging plate 2, thereby realizing the hoisting of the two sets of heat exchange pipeline assemblies 1.

[0020] The working principle and usage process of this utility model are as follows: After the two sets of heat exchange pipe assemblies 1 are assembled, each horizontal pipe 11 of one set of heat exchange pipe assembly 1 is inserted into the first receiving groove 21 on one side of the hanging plate 2, and each horizontal pipe 11 of the other set of heat exchange pipe assembly 1 is inserted into the second receiving groove 22 on the other side of the hanging plate 2. In the initial state, the hook 31 abuts against the positioning rod 4 under the elastic force of the torsion spring 33, and the wedge-shaped surface at the end of the hook 31 is just at the first receiving groove 21 and the second receiving groove 22. Inside the receiving groove 22, by pressing inward, the horizontal tube 11 squeezes the wedge-shaped surface of the hook 31, thereby opening the hook 31, allowing the horizontal tubes 11 of the two sets of heat exchange pipe assemblies 1 to slide smoothly into the tail of the first receiving groove 21 and the hook groove 221 at the tail of the second receiving groove 22. When released, each hook 31 can automatically lock each horizontal tube 11 into the first receiving groove 21 and the hook groove 221 by the torque of the torsion spring 33, realizing the automatic positioning and installation of the two sets of heat exchange pipe assemblies 1.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
