Description

Technical Field

[0001] This application relates to the field of engine cylinder head transportation. Specifically, it relates to a transportation limiting device for an engine cylinder head. Background Technique

[0002] The cylinder head is installed on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. It is often in contact with high-temperature and high-pressure combustion gas, so it bears a large thermal load and mechanical load. The internal of the cylinder head of a water-cooled engine is made with a cooling water jacket. The cooling water holes on the lower end face of the cylinder head communicate with the cooling water holes of the cylinder block, using circulating water to cool high-temperature parts such as the combustion chamber. The cylinder head is also equipped with intake and exhaust valve seats and valve guide holes for installing intake and exhaust valves, as well as intake channels and exhaust channels, etc. The cylinder head of a gasoline engine is machined with holes for installing spark plugs, while the cylinder head of a diesel engine is machined with holes for installing fuel injectors. The cylinder head of an overhead camshaft engine is also machined with camshaft bearing holes for installing the camshaft. The cylinder head is generally cast from gray cast iron or alloy cast iron. Aluminum alloy has good thermal conductivity, which is beneficial to increasing the compression ratio.

[0003] During transportation, the cylinder heads are evenly arranged and placed on the conveying rack for transportation. During transportation, shaking occurs, causing the cylinder heads to collide with the transportation rack, which easily leads to damage to the cylinder heads. Summary of the Invention

[0004] To make up for the above deficiencies, this application provides a transportation limiting device for an engine cylinder head, which solves the above-mentioned problems.

[0005] This application is implemented as follows:

[0006] This application provides a transportation limiting device for an engine cylinder head, including a connection mechanism and a fixing mechanism.

[0007] The connection mechanism includes a fixing frame, a support rod, and a connection seat. There are several fixing frames. One end of the support rod is fixed on the surface of the fixing frame, and the connection seat is fixed at the end of the support rod away from the fixing frame. The fixing frames are stacked in sequence within the connection seat.

[0008] The fixing mechanism includes positioning blocks, clamping seats, cross beams, threaded rods and connecting sleeves. There are two positioning blocks, and the two positioning blocks are symmetrically fixed on the surface of the fixing frame. The surface of the positioning block is provided with a chute and a through groove, and the chute communicates with the through groove. There are several clamping seats, and both ends of the clamping seats are slidably connected in the chute. Bolts are threadedly connected to the surfaces of both ends of the clamping seat, and the bolts are arranged in the through groove and are in clearance fit with the through groove. There are two cross beams, and the two cross beams are slidably connected to the surface of the fixing frame. The two cross beams are respectively arranged outside the two positioning blocks. Two threaded rods are fixedly connected to the surface of each cross beam, and the two ends of the connecting sleeve are respectively threadedly sleeved on the two threaded rods.

[0009] In the above implementation process, place the cylinder head between the clamping seats on the surface of the fixing frame, slide the clamping seats to clamp the cylinder head, fix the left and right surfaces of the cylinder head, and then use bolts to fix both ends of the clamping seat on the positioning block. Similarly, clamp and fix the cylinder head between two clamping seats in sequence. Place the four corners of the fixing frame on the connecting seat and fix them with pins. After fixing the fixing frame in sequence, rotate the connecting sleeve. The two ends of the connecting sleeve are screwed onto the threaded rods to pull the two cross beams inward until the cross beams are tightly attached to the front and back surfaces of the cylinder head for fixation. When disassembly is required, pull out the pins, and the fixing frame can be lifted off in sequence. If the connecting seat catches the fixing frame and makes it inconvenient to lift, the connecting sleeve on the surface of the fixing frame can be rotated upward to support the fixing frame and make it leave the connecting seat. The transportation limiting device for the engine cylinder head can fix the cylinder head on the surface of the fixing frame in sequence and prevent collision during transportation.

[0010] In a specific implementation scheme, through holes are provided on the surface of the connecting seat, and through holes are also provided on the surface of the fixing frame. A pin is inserted into the through holes on the surface of the connecting seat and the through holes on the surface of the fixing frame.

[0011] In the above implementation process, the pin is used to fix between the fixing frame and the connecting seat. When the whole fixing frame needs to be lifted, the fixing frames will not separate.

[0012] In a specific implementation scheme, a shock pad is fixed on the surface of the connecting seat.

[0013] In the above implementation process, the shock pad plays a role in protection and shock absorption when the fixing frames are stacked on each other.

[0014] In a specific implementation scheme, a rope is installed on the surface of the connecting seat, and one end of the rope is tied to the pin.

[0015] In a specific implementation scheme, the rope can prevent the pin from being lost or falling off.

[0016] In a specific implementation scheme, sliders are installed at both ends of the cross beam, and the sliders are slidably connected in the chute.

[0017] In the above implementation process, the sliding block facilitates the sliding connection of the cross beam in the sliding groove in the positioning block.

[0018] In a specific embodiment, a protective pad is installed on the surface of the card seat.

[0019] In a specific implementation, the protective pad plays a protective role. When the holder is stuck on the surface of the cylinder head, once a slight shake occurs, the protective pad can eliminate the damage caused by the collision.

[0020] In a specific implementation manner, a sliding rod is installed on the inner wall of the fixing frame, and both ends of the crossbeam are slidably sleeved on the sliding rod.

[0021] In the above implementation process, the sliding rod is used to slide and connect the crossbeam.

[0022] In a specific embodiment, an anti-slip sleeve is installed on the surface of the connecting sleeve.

[0023] In the above implementation process, the anti-slip sleeve plays a role when the connecting sleeve is rotated by hand.

[0024] In a specific implementation manner, the threaded rod is also fixed to the surface of the fixing frame, the connecting sleeve is also threadedly connected to the threaded rod, and the connecting sleeve is rotatably connected to a support plate at one end away from the threaded rod.

[0025] In the above implementation process, if the connecting seat is stuck on the fixing frame and it is inconvenient to lift it up, the connecting sleeve on the surface of the fixing frame can be rotated to prop up the fixing frame upward to make it leave the connecting seat.

[0026] In a specific embodiment, a nylon strip is installed on the surface of the beam.

[0027] In the above implementation process, the nylon strip plays an anti-collision protection role. BRIEF DESCRIPTION OF THE DRAWINGS
