Description

Technical Field

[0001] The utility model relates to the technical field of large-scale shore machinery equipment, and more specifically, it belongs to a mechanical wind prevention device for large-scale equipment on the dock shore. Background Art

[0002] Large-scale equipment at port dry bulk terminals, such as portal cranes, quay container cranes, and bucket wheel stacker reclaimers, etc., must be equipped with effective wind prevention and gust prevention devices. Currently, in port wind prevention, especially during gusts, the equipment cannot be moved to a fixed anchoring position and can only prevent wind in place. At this time, the operator needs to place iron wedges under the wheels and weld the iron wedges to the rails to ensure that the equipment does not slide under the influence of wind. However, this solution has the following disadvantages:

[0003] (1) The temporary use of iron wedges for wind prevention has poor wind prevention ability and is prone to sliding on the rails;

[0004] (2) Welding the iron wedges in a harsh weather environment cannot ensure the safety of personnel and equipment;

[0005] (3) When removing the iron wedges, defects are left on the rails, making it difficult to level the rails and affecting the safety of the carriages. Summary of the Invention

[0006] The purpose of the utility model is to overcome the deficiencies of the above-mentioned traditional technologies, and provide a mechanical wind prevention device for large-scale equipment on the dock shore, so as to achieve the purpose of ensuring the wind prevention effect of the equipment, reducing potential safety hazards for personnel, and reducing equipment damage.

[0007] The mechanical wind prevention device for large-scale equipment on the dock shore provided by the utility model includes clamping plates, support seats, lead screws, rotating shafts, connecting rods, lifting seats, connecting rods, wedge blocks, and hand wheels; the clamping plates are U-shaped plates, and fixing screws are respectively threadedly engaged at both ends of the openings of the clamping plates; there are a pair of clamping plates, which are arranged in parallel at intervals; the support seats are fixedly connected between the two clamping plates;

[0008] One end of the lead screw is fixedly connected to one end of the rotating shaft; the end of the lead screw far from the rotating shaft is fixedly connected to one end of the connecting rod;

[0009] The rotating shaft is rotatably connected to the center of the support seat; the lead screw is located on one side of the closed end of the clamping plate; a screw hole matching the lead screw is provided in the center of the lifting seat, and the lifting seat is fitted on the lead screw through the screw hole;

[0010] The connecting rods are symmetrically arranged on both sides of the lifting seat, and one end of each connecting rod is respectively hinged to both sides of the lifting seat; wedge blocks are respectively hinged to the ends of the connecting rods far from the lifting seat;

[0011] The hand wheel is fixedly connected to the connecting rod.

[0012] Furthermore, both between the lifting seat and the connecting rod and between the connecting rod and the wedge block are hinged by pin shafts.

[0013] A mechanical wind prevention device for large-scale equipment on the dock shore provided by the present utility model is designed with a clamping plate for clamping and fixing on the equipment track and a wedge block for locking between adjacent wheels of the equipment.

[0014] The clamping plate is designed to be abutted against the top of both sides of the track through fixing screws, so that the clamping plate is clamped and fixed on the equipment track. It can be seen that by increasing the friction force through the fixing screws, the equipment is ensured not to slip, and at the same time, the clamping plate provides an anti-overturning force for the equipment.

[0015] There are two wedge blocks, which are arranged on both sides of the clamping plate through a mechanical lead screw transmission mechanism; the user twists the handwheel to drive the lead screw to rotate, and then drives the lifting seat to move up and down along the lead screw. The up and down movement of the lifting seat will change the angle of the connecting rod, and then drive the wedge block to change the spacing distance between it and the clamping plate, so that the wedge block is closely attached to and locked with the adjacent wheels, ensuring the wind prevention effect of the equipment. Moreover, the adjustment of the spacing between the wedge block and the clamping plate can also make the present utility model suitable for use on equipment with different wheel spacings.

[0016] As can be seen from the above, compared with the traditional scheme, the present utility model ensures the wind prevention effect of the equipment, and has simple operation, does not require fire welding, reduces the safety hazards of operators, and reduces equipment damage.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0024] In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] The present invention provides a mechanical windproof device for large-scale equipment on the dock shore, including a clamping plate 1, a support seat 3, a lead screw 4, a rotating shaft 5, a connecting rod 6, a lifting seat 7, a connecting rod 8, a wedge block 9, a handwheel 10 and a pin shaft 11.

[0027] The clamping plate 1 is a U-shaped plate, and fixing screws 2 are respectively in threaded fit at both ends of the opening of the clamping plate 1. The clamping plates 1 are a pair and are arranged in parallel at intervals. Insertion rods are processed on both sides of the support seat 3, and through holes matching the insertion rods are opened at the middle positions of the closed ends of the two clamping plates 1; the support seat 3 is arranged between the two clamping plates 1 through the cooperation of the insertion rods and the through holes, and the clamping plate 1 and the insertion rods are fixed by screw cooperation.

[0028] It can be seen that the clamping plate 1 is clamped on the equipment track through the open end and is fixed against the track by the fixing screw 2, so as to realize the clamping and fixing of the clamping plate 1 on the track; this solution ensures that the equipment does not slip on the track by increasing the friction force, and at the same time, the clamping plate 1 provides an anti-overturning force for the equipment. The design of the insertion rods on both sides of the support seat 3 and the through holes of the clamping plate 1 ensures the accuracy of the support seat 3 being arranged at the central position between the clamping plates 1.

[0029] One end of the lead screw 4 is welded to one end of the rotating shaft 5; one end of the lead screw 4 far from the rotating shaft 5 is welded to one end of the connecting rod 6. The center of the support base 3 is rotatably connected to the rotating shaft 5 through a bearing; the lead screw 4 is located on one side of the closed end of the clamping plate 1. A threaded hole matching the lead screw 4 is provided in the center of the lifting seat 7, and the lifting seat 7 is fitted on the lead screw 4 through the threaded hole. Connecting rods 8 are symmetrically arranged on both sides of the lifting seat 7, and both sides of the lifting seat 7 are respectively hinged to one end of the connecting rod 8 through a pin shaft 11. Wedge blocks 9 are hinged to the ends of the connecting rods 8 far from the lifting seat 7 through pin shafts 11. The hand wheel 10 is key-connected to the connecting rod 6.

[0030] It can be seen that through the cooperation of the lead screw 4 with the rotating shaft 5 and the bearing, the lead screw 4 realizes rotation on the support base 3. By rotating the hand wheel 10, the lead screw 4 is driven to make a rotational motion, and then the lifting seat 7 is driven to move up and down along the lead screw 4. The up and down movement of the lifting seat 7 will change the angle of the connecting rod 8, and then drive the wedge block 9 to change the spacing distance between it and the clamping plate 1, so that the wedge block 9 is tightly attached to and locked with the adjacent wheels, ensuring the windproof effect of the equipment. Moreover, the adjustment of the spacing between the wedge block 9 and the clamping plate 1 can also make the present utility model adaptable to equipment with different wheel spacings. The wedge block 9 is a wearing part, and a detachable design is adopted between the wedge block 9 and the connecting rod 8, which is convenient for separately replacing the wedge block 9 during later maintenance.

[0031] The specific usage mode and function of this embodiment:

[0032] The present utility model needs to be manually operated. First, buckle the open end of the clamping plate 1 on the equipment track, and then manually move the wedge block 9 to lean against the adjacent wheels on both sides of the clamping plate 1 for pre-positioning; then turn the fixing screw 2, and fix the equipment track by screwing the fixing screw 2 tightly, completing the clamping and fixing of the clamping plate 1 on the track; finally, turn the hand wheel 10 to drive the lead screw 4 to make a rotational motion. Since the wedge block 9 is initially leaning against the wheel and the weight of the wedge block 9 is heavy enough, when the hand wheel 10 is rotated, the lifting seat 7 is limited by the wedge block 9 and will not rotate with the lead screw 4, but will move downward along the lead screw 4. The downward movement of the lifting seat 7 will change the angle of the connecting rod 8, and then drive the wedge block 9 to move towards the wheel until the wedge block 9 is tightly attached to the wheel and the hand wheel 10 cannot be rotated, completing the locking installation of the present utility model.

[0033] When disassembling the present utility model, rotate the hand wheel 10 in the reverse direction. The hand wheel 10 drives the lead screw 4 to rotate in the reverse direction, and the lead screw 4 drives the lifting seat 7 to move upward. The upward movement of the lifting seat 7 changes the angle of the connecting rod 8, and then drives the wedge block 9 to move away from the wheel, and the wedge block 9 and the wheel are unlocked; then, turn the fixing screw 2 in the reverse direction to loosen the contact between the fixing screw 2 and the equipment track until the clamping plate 1 can be taken out from the track; finally, take the present utility model off the equipment track to complete the disassembly.

[0034] In summary, compared with the traditional solution, the utility model ensures the wind protection effect of the equipment, has simple operation, does not require hot work welding, reduces the safety hazards of operators, and reduces equipment damage.
