Description

TECHNICAL FIELD

[0001] The application relates to a hoist for a heat exchanger tube plate, in particular to a heat exchanger tube plate turnover hoist. BACKGROUND

[0002] The tube plate is suitable for a shell-and-tube heat exchanger, a condenser, an evaporator and the like, and plays a role of supporting and fixing the tubes. Since the tube plate needs to be turned over repeatedly for secondary or even multiple machining such as turning, drilling and milling, workers generally adopt a single lifting belt or a processing mode of a baked lifting lug to solve the problem in daily production and processing. The first mode is too dangerous, and the lifting belt is easy to fall off from the center of the workpiece. The second mode needs to remove the baked lifting lug after processing, and a large amount of manpower and material resources are consumed. CONTENT OF THE UTILITY MODEL

[0004] To achieve the above object, the utility model provides the following technical scheme.

[0005] The application discloses a heat exchanger tube plate turnover hoist, which comprises a main supporting rod and two auxiliary supporting rods, the two auxiliary supporting rods are symmetrically connected to the two sides of the tail end of the main supporting rod, the tail end of the two auxiliary supporting rods is respectively formed with a fixed hook body, a movable hook body is slidably arranged on the main supporting rod, a clamping cavity for clamping the heat exchanger tube plate is formed between the fixed hook body and the movable hook body, and the top end of the main supporting rod is rotatably installed on a lifting rope.

[0006] Preferably, in the heat exchanger tube plate turnover hoist, the main supporting rod and the auxiliary supporting rod jointly form a supporting plane of the clamping cavity.

[0007] Preferably, in the heat exchanger tube plate turnover hoist, a locking screw is arranged on the movable hook body.

[0008] Preferably, in the heat exchanger tube plate turnover hoist, the nut of the locking screw abuts against the heat exchanger tube plate.

[0009] Preferably, in the heat exchanger tube plate turnover hoist, the main supporting rod and the two auxiliary supporting rods are arranged in a Y shape.

[0010] Compared with the prior art, the tube plate turnover lifting appliance is suitable for thick and thin steel plates, forgings and various shaped parts, and is particularly suitable for machining turnover of multiple times of finishing. BRIEF DESCRIPTION OF DRAWINGS

[0015] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0016] In combination with Figs. 1-3 As shown in the figure, the heat exchanger tube plate turnover lifting appliance 100 comprises a main supporting rod 101 and two auxiliary supporting rods 102, the two auxiliary supporting rods 102 are symmetrically connected to the two sides of the tail end of the main supporting rod 101, the tail end of the two auxiliary supporting rods 102 is respectively formed with a fixed hook body 103, a movable hook body 104 is slidably arranged on the main supporting rod 101, a clamping cavity 105 for clamping the heat exchanger tube plate 200 is formed between the fixed hook body 103 and the movable hook body 104, and the top end of the main supporting rod 101 is rotatably installed on a lifting rope. The main supporting rod 101 and the auxiliary supporting rod 102 jointly form a supporting plane of the clamping cavity 105. The movable hook body 104 is provided with a locking screw 106. The nut of the locking screw 106 abuts against the heat exchanger tube plate 200. The main supporting rod 101 and the two auxiliary supporting rods 102 are arranged in Y shape.

[0017] Specific use, first move the hook to hook two fixed hook body heat exchanger tube plate (at this time the heat exchanger tube plate is generally empty placed on the cushion, so you can insert the bottom hook, then move the hook body to three hook body hook, then through the locking screw lock, then through the lifting rope to the top of the main branch rod hoisting, you can achieve the turnover.

[0018] It should be noted that in this text, such as the first and second relationship terms are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.
