Description

Technical Field

[0001] The utility model relates to a top cover turning vehicle, in particular to a top cover turning vehicle which can be locked and turned stably. Background Art

[0002] In the field of manufacturing technology, especially in the field of mechanical automation equipment, the maintenance and overhaul of large-scale equipment is a crucial process. Large-scale equipment often has complex structures and large volumes, and the overhaul, maintenance, and transportation of its covers require significant manpower and material resources. Furthermore, due to the unique characteristics of these equipment, the reversal of its covers requires precise operation and control to ensure normal operation of the equipment and the safety of the operators.

[0003] In the existing technology, the upper cover of large equipment is usually flipped by manual flipping or a flipping vehicle. Manual flipping is done by manually flipping the upper cover, which requires a lot of physical strength and can easily cause equipment damage or personal injury due to improper operation. The flipping vehicle flips the upper cover by fixing the edge of the upper cover through the support and fixing structure of the flipping vehicle, thereby achieving flipping at any angle. However, in the existing technology, since the upper cover of large equipment is heavy and large, the upper cover often shakes during assembly and maintenance, resulting in low assembly accuracy, difficulty in maintenance, and even threats to the lives of workers. Although the ordinary bracket locking mechanism is stable, it supports fewer flipping angles and is greatly limited by the bracket travel. The ordinary latch-type locking mechanism lacks effective support, making it impossible for the latch to stably lock the flipping mechanism. In addition, the heavy upper cover easily causes the latch to wear, and the friction of the latch insertion increases, causing the latch to fail. In addition, due to the limited locking capacity of the flipping vehicle wheels, the flipping vehicle is prone to sliding during assembly, affecting assembly accuracy and progress. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a stably locked and flippable upper cover flip car, which can greatly improve the safety and stability of the flip car, ensure assembly accuracy, reduce the wear of the latch, and extend the service life of the latch.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to provide a stably locked and flippable upper cover flipping vehicle, comprising a vehicle frame, wherein a gear transmission device and a fixed pin seat are installed on the vehicle frame; the gear transmission device comprises a gearbox, a driving gear and a driven gear, the gearbox is connected to the driving gear through a gear shaft, and the driving gear is meshed with the driven gear; a fixing hole for assembling the upper cover is arranged on the driven gear, a bushing is provided in the fixing hole, a fixing pin is installed on the fixing pin seat, the fixing pin seat has a guide groove and two positioning grooves at the front and rear ends, the guide groove passes through the fixing pin seat, and the fixing pin has a ball head handle; when the upper cover is rotated to a preset angle, the fixing pin is inserted into the fixing hole on the driven gear and slides into the bushing to lock the flipping mechanism, and at the same time the ball head handle is stuck in the positioning groove at the front end of the fixing pin seat.

[0006] Furthermore, the bushing is a self-lubricating bushing, and the fit between the fixing hole and the bushing is a clearance fit.

[0007] Furthermore, the guide groove between the fixing pin seat close to the gear end and the positioning groove is a closed guide groove.

[0008] Furthermore, there are multiple fixing holes on the driven gear and they are evenly arranged along the circumference of the gear.

[0009] Furthermore, the upper cover support frame includes two support beams and a cross beam, the support beams and the cross beams are welded together to form a rectangular frame, and rotating shafts are welded at the bottom of both sides of the support beams; the frame is a rectangular frame, and the lateral dimension of the frame is larger than the lateral dimension of the upper cover support frame to form a platform.

[0010] Furthermore, an upper cover fixing block is provided on the upper cover support frame, and upper cover limiting blocks are provided on both sides of the upper cover fixing block; the upper cover fixing block is connected to the upper cover support frame through fixing studs, and the upper cover limiting blocks are welded to the upper cover support frame.

[0011] Compared with the existing technology, the present invention has the following beneficial effects: 1. Improved safety: The present invention is equipped with a fixed pin seat and a fixed pin.

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Figure 1 This is a schematic diagram of the structure of the top cover flipping vehicle with stable locking and flipping according to the utility model; Figure 2 It is a schematic diagram of the cooperation between the fixing pin and the fixing pin seat in the upper cover flip car of the present invention.

[0018] See Figure 1 and Figure 2 The utility model provides a stable, locked and flipping upper cover flipping vehicle, which includes a frame 8, wherein a gear transmission device and a fixed pin seat 11 are installed on the frame 8; the gear transmission device includes a gearbox 5, a driving gear 4 and a driven gear 6, the gearbox 5 is connected to the driving gear 4 through a gear shaft, and the driving gear 4 is meshed with the driven gear 6; a fixing hole for assembling the upper cover is arranged on the driven gear 6, a bushing 15 is provided in the fixing hole, and a fixing pin 10 is installed on the fixing pin seat 11, the fixing pin seat 11 has a guide groove 14 and two positioning grooves 17 at the front and rear ends, the guide groove 14 passes through the fixing pin seat 11, and the fixing pin 10 has a ball handle 16; when the upper cover is rotated to a preset angle, the fixing pin 10 is inserted into the fixing hole on the driven gear 6 and slides into the bushing 15 to lock the flipping mechanism, and at the same time, the ball handle 16 is stuck in the positioning groove 17 at the front end of the fixing pin seat 11.

[0019] This utility model solves the problem of shaky lids on lid-turning vehicles. Due to the heavy weight and bulk of the lid, shaky lids are prone to occur during flipping, and there is a lack of an effective and stable locking device. This utility model utilizes a bolt-type fixing pin and a corresponding fixing pin holder. The fixing pin holder provides stable support for the fixing pin, which is inserted into the fixing hole of the transmission gear of the flip mechanism to achieve the purpose of stable locking of the flip mechanism.

[0020] The problem of easy wear of the latch and high friction when inserting the latch is addressed. Since the latch needs to be adjusted and flipped many times, it needs to be inserted and pulled out many times. The high friction and pressure can easily wear the latch, causing the latch to fail or even break. The bushing 15 used in the present invention is preferably a self-lubricating bushing, and the fitting between the fixing hole and the bushing 15 is a clearance fit. The use of a self-lubricating bushing can facilitate the insertion of the latch while protecting the latch, reducing the wear of the latch and extending the service life of the latch. The self-lubricating bushing is a standardized part with low cost and is easy to maintain and replace.

[0021] To address the problem of the flip cart easily moving during assembly. Due to the limited locking capacity of the flip cart's wheels, the flip cart is prone to sliding during assembly. The present invention enlarges the lateral support frame at the bottom of the frame, making the lateral dimensions of the frame 8 larger than those of the upper cover support frame 1, forming a step. While ensuring sufficient frame support, the step can serve as a step, allowing workers to stand on the frame to work.

[0022] The upper cover flip car provided by the utility model is installed and used as follows:

[0023] Step 1: Prepare the tipping vehicle and gear transmission. The tipping vehicle includes a frame 8 and four casters 9. The bottom transverse support beam of the frame 8 is larger than the upper cover support frame 1. The frame 8 is mounted with a gear transmission and a bearing seat 7. The gear transmission includes a gearbox 5, a driving gear 4, and a driven gear 6. The gearbox 5 is connected to the driving gear 4 via a gear shaft, and the driving gear 4 meshes with the driven gear 6. The driven gear 6 is provided with fixing holes that meet the requirements of upper cover assembly and maintenance. The holes are fitted with self-lubricating bushings 15, which are clearance fits.

[0024] Step 2: Prepare the upper cover support frame 1, the upper cover limit block 2 and the upper cover fixing block 13. The upper cover support frame 1 includes two support beams and a cross beam. The support beams and the cross beams are welded together to form a rectangular frame, and the rotating shafts are welded at the bottom of both sides of the support beams. The upper cover fixing block 13 is fixed on the upper cover support frame 1, and the upper cover fixing block 13 is connected to the upper cover support frame 1 by fixing studs 3. The upper cover limit block 2 is welded to the upper cover support frame 1 and is located on both sides of the upper cover fixing block 13. The rectangular frame can be equipped with an extended support assembly 12, which consists of a support beam, an upper cover limit block 2, an upper cover fixing block 13 and a locking structure.

[0025] Step 3: Install the flip car. Connect the rotating shaft on one end of the upper cover support frame 1 to the driven gear shaft hole of the gear transmission device through a flat key and install it on the bearing seat. The other end of the rotating shaft is directly connected to the bearing seat on the frame.

[0026] Step 4: Prepare the fixing pin seat 11 and the fixing pin 10. The fixing pin seat 11 is fixed to the frame 8 of the flip car by screws, and the fixing pin 10 is opposite to the fixing holes arranged circumferentially on the driven gear 16. The fixing pin 10 is installed on the fixing pin seat 11. The fixing pin seat 11 has a guide groove 14 and two positioning grooves 17. The guide groove 14 runs through the fixing pin seat 11, and the fixing pin 10 has a latch and a ball handle 16. After determining the distance between the fixing pin seat 11 and the gear, determine the length and stroke of the fixing pin 10. It is required that the fixing pin 10 can be fully inserted into the fixing hole on the gear, and confirm the position of the positioning groove 17. A closed guide groove is used between the fixing pin seat 11 near the gear end and the positioning groove 17 to prevent the fixing pin 10 from detaching from the fixing pin seat 11 and failing to lock during flipping. An open guide groove is used after the positioning groove 17 to facilitate the flexible rotation of the ball handle 16 of the fixing pin and the flexible insertion and removal of the latch.

[0027] Step 5: Install the upper cover. Push the turning vehicle to the vicinity of the vacuum coating equipment, hoist the upper cover onto the upper cover support frame 1 of the turning vehicle, and fix the upper cover with the upper cover fixing block 13 and fixing studs.

[0028] Step 6: Flip the top cover. Manually rotate the outer handle of the gearbox 5, driving the driving gear 4, which in turn rotates the top cover with the driven gear 6. Because the transmission ratio between the driving gear 4 and the driven gear 6 is large, only a small torque is required to flip the top cover.

[0029] Step 7: Lock the flip mechanism. When the upper cover is rotated to the desired angle, insert the fixing pin 10 into the fixing hole on the driven gear 6. The fixing pin 10 and the bushing 15 form a clearance fit. The fixing pin 10 slides into the self-lubricating bushing, locking the flip mechanism and preventing the upper cover from rotating. The ball handle 16 snaps into the positioning groove at the front end of the fixing pin seat 11 to prevent the fixing pin from moving accidentally.

[0030] Step 8: Transport the equipment. Since the flip mechanism is supported by the frame 8 and casters 9, the upper cover can be easily transported.

[0031] Step 9: Assemble and maintain the upper cover. After the vehicle arrives at the destination, the casters 9 are locked and the assembler can stand on the bottom frame 8 to assemble and maintain the components of the upper cover.

[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make slight modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
