Description

Technical Field

[0001] This application relates to the technical field of transportation operation fixing devices, and in particular to a fixing device for engine transportation. Background Art

[0002] After the engine is processed at the production site, it needs to be transported to the place of use. At this time, engine transportation operations are involved. Engine transportation involves multiple links and precautions. Since the engine is a precision and heavy equipment, it must be well packaged and fixed during transportation to prevent damage or displacement during transportation. Usually, professional packaging materials and fixing devices are required to ensure the safety of the engine.

[0003] A prior art discloses an engine transportation bracket, which includes a main frame, a pusher, casters and a support block. The main frame includes two identical vertical rods, a first cross bar, a second cross bar and a third cross bar. The two vertical rods are parallel to each other, and both ends are respectively fixed on the first cross bar and the third cross bar. The second cross bar is located between the first cross bar and the third cross bar, and both ends are respectively fixed on the two vertical rods. The casters are respectively fixed at the bottom ends of the first cross bar and the third cross bar. The support block includes five, one of which is fixed on the second cross bar, and the remaining four are symmetrically fixed on the two vertical rods. The pusher is fixed on the top surface of the first cross bar; a U-shaped groove is provided at the top end of the support block, and a fixing hole is provided in the U-shaped groove. The support block is fixed to the vertical rod and the second cross bar by screws.

[0004] In view of the above related technologies, when transporting the engine, it is necessary to first lift the engine above the main frame by a lifting device, and then fix the engine to the main frame by external objects such as straps. At the same time, during the overall transportation of the bracket and the engine by the vehicle, due to the changes in the vehicle speed and road conditions, the bracket may move relative to the vehicle, resulting in adjacent engines colliding. Therefore, it is necessary to additionally cover the engine with an anti-collision structure. Therefore, during transportation, operators are required to fix the engine and cover the anti-collision structure, which takes a long time and affects the efficiency of engine transportation. Summary of the Invention

[0005] In order to shorten the time consumed for engine fixing and covering the outer anti-collision structure to improve the efficiency of engine transportation, this application provides a fixing device for engine transportation.

[0006] The fixing device for engine transportation provided by this application adopts the following technical solutions: A fixing device for engine transportation, comprising: A support frame, on which a bearing plate is slidably connected, and the bearing plate is horizontally arranged and slides in the vertical direction; A plurality of fixed seats, the fixed seats are connected to the support frame, and the bearing plate is located within the accommodation interval surrounded by the plurality of fixed seats; A plurality of rotating protective columns, the rotating protective columns are rotatably connected to the fixed seats, and one end of the rotating protective column can abut against the bearing plate; A plurality of fixed air bags, the rotating protective column is hollow and has an opening on one side, the fixed air bag is connected to the rotating protective column, and after the fixed air bag is inflated, it extends out to the accommodation interval from the opening side.

[0007] By adopting the above technical solution, the support frame is placed on the transport vehicle, and then the engine is placed on the bearing plate through the hoisting device, or the engine is first placed on the bearing plate through the hoisting device, and then the fixing device and the engine as a whole are hoisted onto the transport vehicle. Among them, after the engine is hoisted onto the bearing plate by the hoisting device, due to the influence of the gravity of the engine, the bearing plate slides downward. During the sliding process of the bearing plate, it abuts against the rotating protective column, causing the rotating protective column to rotate around the fixed seat until the bearing plate slides in place. At this time, the rotating protective column is in a nearly vertical state and encloses the engine. Then, an external air pump or an internal air pump is used to inflate the fixed air bag until the fixed air bag abuts against the outside of the engine. At the same time, since the part of the fixed air bag above the engine will not be blocked by the engine, the distance of inward expansion is greater than the section corresponding to the engine. Therefore, it can also keep the engine tightly abutted against the bearing plate, and the fixed air bag can also play a role in anti-collision; the designed fixing device for engine transportation can provide a placement area for the engine through the support frame and the bearing plate, provide a rotation fulcrum for the rotating protective column through the fixed seat, and realize the enclosure and fixation of the engine during the hoisting and placement process of the engine through the cooperation of the rotating protective column and the fixed air bag, shortening the time consumed for engine fixation and the covering of the outer anti-collision structure, thereby improving the efficiency of engine transportation.

[0008] In a specific feasible implementation scheme, a return spring is connected between the bearing plate and the support frame, and an elastic return rope is connected between the bearing plate and the rotating protective column.

[0009] By adopting the above technical solution, the designed return spring and elastic return rope can keep the rotating protective column in a horizontal state, so as to provide the largest inlet for the engine during the hoisting process.

[0010] In a specific feasible implementation scheme, a plurality of sliding guide rods are vertically connected to the bearing plate, the sliding guide rods pass through the support frame, and the sliding guide rods are slidably connected to the support frame.

[0011] By adopting the above technical solution, the designed sliding guide rods can facilitate the control of the sliding direction of the bearing plate.

[0012] In a specific feasible implementation, it further includes a plurality of adsorption and fixing units, and the adsorption and fixing units include: An adsorption cylinder, the adsorption cylinder is connected to the support frame, and both ends of the adsorption cylinder are provided with openings; A piston disk, the piston disk is slidably connected inside the adsorption cylinder, and the piston disk divides the inner cavity of the adsorption cylinder into two chambers; A linkage rope, one end of the linkage rope is connected to the piston disk, the other end extends out from the opening of the top wall of the adsorption cylinder and is connected to the support frame, and the lower end of the sliding guide rod is connected to the linkage rope.

[0013] By adopting the above technical solution, first place the support frame on the transport vehicle, then place the engine on the bearing plate through a hoisting device. Then, during the process that the bearing plate slides downward against the elastic force of the return spring under the influence of the gravity of the engine, the sliding guide rod slides downward synchronously. While the sliding guide rod slides downward, a force is applied to the linkage rope, and the linkage rope applies a force to the piston disk to make the piston disk slide upward inside the adsorption cylinder, so that the pressure in the cavity formed among the adsorption cylinder, the piston disk and the transport vehicle is reduced, thereby realizing adsorption and fixation, and reducing the possibility of adverse effects on the engine caused by speed changes or bumps during the driving of the transport vehicle; the designed adsorption and fixing unit, through the cooperation of the adsorption cylinder, the piston disk and the linkage rope, can realize the adsorption and fixation of the support frame, reduce the possibility of relative displacement between the support frame and the transport vehicle, and thus reduce the possibility of adverse effects on the engine caused by speed changes or bumps during the driving of the transport vehicle.

[0014] In a specific feasible implementation, the linkage rope passes through the sliding guide rod, and the linkage rope is slidably connected to the sliding guide rod.

[0015] By adopting the above technical solution, the designed linkage rope that passes through and is slidably connected to the sliding guide rod can realize the reliability of the linkage between the linkage rope and the sliding guide rod, and avoid the possibility that the linkage rope and the sliding guide rod are separated due to reasons such as the shaking of the linkage rope.

[0016] In a specific feasible implementation, a sealing rubber ring is embedded at the lower end of the adsorption cylinder.

[0017] By adopting the above technical solution, the designed sealing rubber ring can better achieve the sealing effect.

[0018] In a specific feasible implementation, a connecting frame is slidably connected to the support frame, the sliding direction of the connecting frame is the same as the sliding direction of the bearing plate, and the connecting frame is connected to the adsorption cylinder, and the adsorption cylinder is slidably connected to the support frame.

[0019] By adopting the above technical solution, the designed connecting frame can realize the movement of the far side of multiple suction cylinders away from the ground, thereby extending the service life of the sealing rubber ring embedded at the lower end of the suction cylinder.

[0020] In a specific feasible implementation, an adjusting bolt is threadedly connected to the support frame. The adjusting bolt passes through the connecting frame, and the adjusting bolt is rotatably connected to the connecting frame.

[0021] By adopting the above technical solution, the designed adjusting bolt can realize the position adjustment of the connecting frame, and further realize the position adjustment of the suction cylinder.

[0022] In a specific feasible implementation, the end of the rotating protection column away from the bearing plate is bent upward.

[0023] By adopting the above technical solution, the designed rotating protection column with an upward bending setting can, when the fixed airbag is inflated, prompt the fixed airbag to press against the top of the engine, thereby keeping the engine in contact with the bearing plate, and further keeping the position of the bearing plate stable, thus realizing the position stability of the rotating protection column.

Detailed implementation manners

[0032] The following will further describe the present application in detail in conjunction with the attached Figures 1-4 drawings.

[0033] An embodiment of the present application discloses a fixing device for engine transportation.

[0034] Referring to Figure 1 , a fixing device for engine transportation includes a support frame 1, a bearing plate 2 and a plurality of fixed seats 3. The bearing plate 2 is horizontally arranged and slidably connected to the support frame 1. The sliding direction of the bearing plate 2 is vertically arranged. The fixed seats 3 are welded and fixed to the support frame 1, and the plurality of fixed seats 3 are evenly distributed around the periphery of the bearing plate 2. The bearing plate 2 is located within the accommodation area surrounded by the plurality of fixed seats 3.

[0035] Referring to Figure 1 , in order to achieve anti-collision protection for the engine while fixing the engine, the fixing device for engine transportation further includes a rotating protection column 4 and a plurality of fixed airbags 41. The rotating protection column 4 is rotatably connected to the fixed seat 3 through a hinge shaft. The central axis of the hinge shaft is horizontally arranged, and one end of the rotating protection column 4 can abut against the bearing plate 2. The bearing plate 2 slides vertically under the gravity of the engine, so that the rotating protection column 4 rotates around the hinge shaft until the bearing plate 2 slides in place. At this time, the rotating protection column 4 rotates from the horizontal state to the vertical state, forming a cavity surrounding the engine. The rotating protection column 4 is hollow and has an opening on the side facing the engine. The fixed airbag 41 is connected to the rotating protection column 4, and after the fixed airbag 41 is inflated, it extends from the opening side into the accommodation area until the engine is fixed.

[0036] Referring to Figure 1, specifically, one end of the rotating protective column 4 away from the bearing plate 2 is bent upward. In this application, one end of the rotating protective column 4 away from the bearing plate 2 can be bent upward in an arc shape or in a straight line shape; through the rotating protective column 4 bent upward, when the fixing airbag 41 is inflated, the fixing airbag 41 can be urged to press against the top of the engine, thereby keeping the engine in contact with the bearing plate 2, and further keeping the position of the bearing plate 2 stable, so as to realize the position stability of the rotating protective column 4.

[0037] Refer to Figure 2 , further, in order to realize the automatic reset of the bearing plate 2 and the rotating protective column 4 and reduce the manual participation, a reset spring 11 is fixedly welded between the bearing plate 2 and the support frame 1. The elastic force direction of the reset spring 11 is the same as the sliding direction of the bearing plate 2, and an elastic force reset rope 21 is connected between the bearing plate 2 and the rotating protective column 4 by screws. The reset spring 11 applies force to the bearing plate 2, causing the bearing plate 2 to slide upward in the vertical direction. While the bearing plate 2 slides, the rotating protective column 4 is pulled by the elastic force reset rope 21, so that the rotating protective column 4 returns to the horizontal state; in this application, the number of the reset springs 11 can be one or multiple, as long as the bearing plate 2 can be reset.

[0038] Refer to Figure 2 , specifically, a plurality of sliding guide rods 5 are fixedly welded on the bearing plate 2. The sliding guide rods 5 are perpendicular to the bearing plate 2, and the sliding guide rods 5 pass through the support frame 1 and are slidably connected to the support frame 1.

[0039] Refer to Figure 3 and Figure 4 , furthermore, in order to realize the relative position stability between the support frame 1 and the transport vehicle and reduce the influence of the vehicle running state on the engine, the fixing device for engine transportation further includes a plurality of adsorption fixing units 6. The adsorption fixing unit 6 specifically includes an adsorption cylinder 61, a piston disk 62 and a linkage rope 63. The adsorption cylinder 61 is connected to the support frame 1, and both ends of the adsorption cylinder 61 are open. The central axis of the adsorption cylinder 61 is vertically arranged. The piston disk 62 is slidably connected in the adsorption cylinder 61, and the piston disk 62 divides the inner cavity of the adsorption cylinder 61 into two chambers. One end of the linkage rope 63 is connected to the piston disk 62, and the other end extends out from the top opening of the adsorption cylinder 61 and is connected to the support frame 1, and the lower end of the sliding guide rod 5 is connected to the extended section of the linkage rope 63; through the cooperation of the adsorption cylinder 61, the piston disk 62 and the linkage rope 63, the adsorption fixation of the support frame 1 can be realized, reducing the possibility of relative displacement between the support frame 1 and the transport vehicle, thereby reducing the possibility of adverse effects on the engine caused by speed changes or bumps during the running of the transport vehicle.

[0040] Refer to Figure 3 and Figure 4Specifically, the linkage rope 63 is arranged through the sliding guide rod 5, and the linkage rope 63 is slidably connected to the sliding guide rod 5. The linkage rope 63 passing through and slidably connected to the sliding guide rod 5 can achieve the reliability of the linkage between the linkage rope 63 and the sliding guide rod 5, and avoid the possibility of the linkage rope 63 being separated from the sliding guide rod 5 due to the shaking of the linkage rope 63 and the like; and a sealing rubber ring 64 is embedded at the lower end of the adsorption cylinder 61 to increase the sealing between the adsorption cylinder 61 and the transport vehicle, so as to better achieve the adsorption and fixing effect.

[0041] Reference Figure 4 A connecting frame 7 is slidably connected to the support frame 1, and the sliding direction of the connecting frame 7 is consistent with the sliding direction of the bearing plate 2. The connecting frame 7 is welded and fixed to the adsorption cylinder 61, and the adsorption cylinder 61 is slidably connected to the support frame 1, so that multiple adsorption cylinders 61 can be moved away from the ground, thereby extending the service life of the sealing rubber ring 64 embedded at the lower end of the adsorption cylinder 61; in order to realize the position control of the connecting frame 7, an adjusting bolt 8 is threadedly connected to the support frame 1, and one end of the adjusting bolt 8 is rotatably connected to the connecting frame 7. When the adjusting bolt 8 rotates, it rotates relative to the connecting frame 7, and pulls the connecting frame 7 to slide through the connection at the rotating connection; in the present application, the sliding guide rod 5 can be staggered with the connecting frame 7, and the sliding guide rod 5 can also pass through and be slidably connected to the connecting frame 7. The implementation principle of the fixing device for transporting an engine in the embodiment of the present application is as follows: placing the support frame 1 on the transport vehicle, and then placing the engine on the load-bearing plate 2 by means of a lifting device, or first placing the engine on the load-bearing plate 2 by means of a lifting device, and then lifting the fixing device and the engine as a whole onto the transport vehicle, wherein, after the engine is hoisted onto the load-bearing plate 2 by means of the lifting device, the load-bearing plate 2 slides downward due to the influence of the gravity of the engine, and during the sliding process of the load-bearing plate 2, it contacts the rotating protective column 4, so that the rotating protective column 4 rotates around the fixing seat 3 until the load-bearing plate 2 slides down into place, at which time the rotating protective column 4 is in a nearly vertical state and encloses the engine, and then an external air pump or a built-in air pump is used to pump air into the fixed seat 3. The bag 41 is inflated until the fixed airbag 41 abuts against the outside of the engine. At the same time, since the fixed airbag 41 is located above the engine, there is no obstruction from the engine, and the inward expansion distance is greater than the interval section corresponding to the engine. Therefore, the engine can be kept tightly against the supporting plate 2. At the same time, the fixed airbag 41 can also play an anti-collision role; the support frame 1 and the supporting plate 2 can provide a placement area for the engine, and the fixed seat 3 can provide a rotation fulcrum for the rotating protective column 4. The rotating protective column 4 cooperates with the fixed airbag 41 to realize the enclosure and fixation of the engine during the process of engine hoisting and placement, shortening the time consumed by the engine fixation and the outer anti-collision structure covering, thereby improving the efficiency of engine transportation.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
