DETAILED DESCRIPTION

[0030] 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.

[0031] refer to Figure 1-2 , an automatic hoisting device for processing glass fiber reinforced plastic circulating tanks, comprising: a crossbeam 1; a moving beam 2, which is installed at the bottom of the crossbeam 1 along the axial direction of the crossbeam 1, and two of them are symmetrically installed; a clamping mechanism 3, which is installed on the opposite side of the two moving beams 2, and is used to clamp the glass fiber reinforced plastic plate 7; a driving component 4, which is installed on the crossbeam 1 to drive the two moving beams 2 to move back and forth along the axial direction of the crossbeam 1; reference Figure 3-4, a positioning assembly 5, which is installed at the bottom of the crossbeam 1 and between the two moving beams 2, has a vertically elastic positioning plate 51, a trigger portion 52 installed on the top of the positioning plate 51, and a trigger 53 installed above the trigger portion 52 and spaced apart to control the driving assembly 4. It can be understood that the guiding of the moving beam 2 and the crossbeam 1 can be coordinated by an axial hole guide or a slide rail guide. The clamping mechanism 3 can be a pneumatic clamping mechanism 3, a spiral clamping mechanism 3, etc. The driving assembly 4 can be a device that drives the moving beam 2 to move, such as an electric push rod, a screw 41 transmission, etc. The trigger 53 can be a micro switch, a touch switch, a travel switch, a proximity switch, etc. The trigger 53 is used in conjunction with a control system, and the control system controls the driving assembly 4 to work. In this way, during hoisting, the lifting equipment moves the crossbeam 1 to drive the entire device to move, so that the positioning plate 51 on the positioning assembly 5 is pressed on the glass fiber reinforced plastic plate 7, and moves down until the trigger part 52 contacts the trigger 53. The trigger 53 is turned on to enable the driving assembly 4 to work and drive the moving beam 2 and then drive the clamping mechanism 3 to move toward each other and press against the two sides of the glass fiber reinforced plastic plate 7. Finally, the glass fiber reinforced plastic plate 7 is clamped by the clamping mechanism 3.

[0032] Optionally, in some embodiments, the axial direction of the moving beam 2 is perpendicular to the axial direction of the cross beam 1, and at least two clamping mechanisms 3 are installed on each moving beam 2. It can be understood that the glass fiber reinforced plastic plate 7 is generally square, and the opposite sides are parallel, so the two moving beams 2 are also arranged in parallel. The center of the moving beam 2 is installed on the cross beam 1, and the two clamping mechanisms 3 are installed at the axial ends of the moving beam 2, that is, on both sides of the axial vertical direction of the cross beam 1. In this way, the glass fiber reinforced plastic plate 7 can be clamped more stably.

[0033] Optionally, in some embodiments, the clamping mechanism 3 includes: a fixed plate 31 installed on the side of the moving beam 2 close to the positioning assembly 5; a movable plate 32 spaced above the fixed plate 31; and a telescopic driver 33 installed on the moving beam 2 and driving the movable plate 32 to move toward the fixed plate 31 to clamp the glass fiber reinforced plastic plate 7. It can be understood that the telescopic driver 33 can be a cylinder, an electric push rod or other devices, which are fixedly installed on the beam 1, or indirectly installed on the beam 1 through a connecting plate or other structure. The output end of the telescopic driver 33 faces downward, and the movable plate 32 can be directly installed on the output end of the telescope. The movable plate 32 can also be installed on the beam 1 in a vertical sliding manner. In this way, when the glass fiber reinforced plastic plate 7 is located on the fixed plate 31, the movable plate 32 is driven by the telescopic driver 33 to move downward and press on the glass fiber reinforced plastic plate 7 for clamping.

[0034] Optionally, in some embodiments, reference Figure 3, the cross beam 1 is provided with a cavity 11 inside, and a slideway 12 communicating with the cavity 11 is provided at the bottom; the driving assembly 4 includes: a screw 41, which is horizontally and rotatably installed in the cavity 11; two slide sleeves 42 are provided, one end of which is threadedly sleeved on the screw 41, and the other end passes through the slideway 12 and is connected to the moving beam 2, and the threads on the two slide sleeves 42 have opposite rotation directions; a rotary driver 43 is connected to the screw 41 for rotation transmission and then drives the screw 41 to rotate. It can be understood that the screw 41 transmission structure is adopted here, and the slideway 12 plays a guiding and limiting role for the slide sleeve 42. The shaft hole guide matching structure can also be adopted here. Since the spiral rotation directions of the two slide sleeves 42 are opposite, when the screw 41 rotates forward and backward, the two slide sleeves 42 move apart and close together. The rotary driver 43 can be a servo motor, which can be installed on the cross beam 1, and the output end is directly connected to the screw 41, or it can be connected through transmission parts such as gears. In this way, the rotary driver 43 drives the screw rod 41 to rotate, so that the sliding sleeve 42 drives the moving beam 2 to move, so that the clamping mechanism 3 abuts against both sides of the glass fiber reinforced plastic plate 7 .

[0035] Optionally, in some embodiments, reference Figure 3-4 , the positioning assembly 5 also includes: a guide portion 55 installed at the bottom of the beam 1; a limit portion 54 installed on the positioning plate 51 and vertically connected to the guide portion 55; when the top of the limit portion 54 abuts against the beam 1, the clamping mechanism 3 is directly opposite to the glass fiber reinforced plastic plate 7. Further, the guide portion 55 and the limit portion 54 are both tubular structures and are guided and sleeved. It can be understood that the trigger portion 52 is an upwardly protruding structure. In the free state, the top of the limit portion 54 is spaced from the bottom of the beam 1, and the trigger portion 52 is also spaced from the trigger 53. Only when the positioning plate 51 moves down and presses on the glass fiber reinforced plastic plate 7, the limit portion 54 moves up and abuts against the bottom of the beam 1. At this time, the glass fiber reinforced plastic plate 7 is horizontally located between the fixed plate 31 and the movable plate 32. At the same time, the trigger portion 52 also abuts against the trigger 53, thereby triggering the driving assembly 4 to drive the clamping mechanism 3 to move. Furthermore, a spring 56 is installed between the positioning plate 51 and the beam 1, and the trigger portion 52, the trigger 53, and the spring 56 are all located in the guide portion 55 and the limiting portion 54. The spring 56 can separate the top of the limiting portion 54 from the bottom of the beam 1, and the limiting portion 54 has elastic resistance when it moves upward.

[0036] In some embodiments, a connection seat 6 for connecting a crane is installed in the middle of the top of the crossbeam 1. Here, a through hole can be opened on the connection seat 6, and the connection can be made by hanging a hook on the through hole, or the crane can be connected to the connection seat 6 by a connecting piece such as a screw 41 or a rivet.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
