Description

Technical Field

[0001] This utility model relates to the field of jacking technology, and in particular to a jacking for loading and unloading vehicles at a dock. Background Technology

[0002] A gantry crane is a device used to restrain vehicles when loading and unloading them at a dock. When using a gantry crane, a hook is attached to one end of the crane, and then a connecting sleeve at the bottom of the connecting belt is placed on the bottom of the car wheel. This allows the crane to transport vehicles at the dock.

[0003] The inventors discovered in their daily work that the gantry still has at least the following problems: When using the gantry, the hook is hung on one end of the crane, and then the connecting sleeve set at the bottom of the connecting belt is put on the bottom of the car wheel. This allows the crane to transport vehicles on the dock. However, in actual use, the connecting sleeve needs to be put on the bottom of the car wheel manually, which is quite troublesome and thus affects the loading and unloading efficiency to some extent. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gantry for loading and unloading vehicles at docks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gantry for loading and unloading vehicles at a dock, comprising a support frame, a connecting strap at the bottom of the support frame, a connecting rope at the top of the support frame, a hook fixedly connected to the top of the connecting rope, a connecting sleeve fixedly connected to the bottom of the connecting strap, a connecting device on one side of the connecting sleeve, and a fixing device on one side of the support frame. The connecting device includes a first fixing strap, a connecting groove on one side of the connecting sleeve, a fixed connection between one side of the connecting sleeve and one end of the first fixing strap, a fixing frame fixedly connected to the end of the connecting sleeve away from the first fixing strap, a sliding connection between the inner wall of the fixing frame and the first fixing strap, a fixing hole on one side of the first fixing strap, and a fixing rod slidably inserted through one side of the fixing frame, the fixing rod being slidably connected to the inner wall of the fixing hole.

[0006] The effect achieved by the above components is as follows: when using the connecting device, the connecting sleeve is put on the surface of the tire through the connecting groove, and then the first fixing strap is wrapped around the side of the tire away from the connecting sleeve. The first fixing strap is then inserted into the inside of the fixing frame, and the fixing rod is inserted into the inside of the fixing hole after passing through the fixing frame. This can restrict one end of the first fixing strap inside the fixing frame, thus making it easy to restrict the connecting sleeve to the surface of the car tire.

[0007] Preferably, a first spring is sleeved on the surface of the fixing rod, one end of the first spring is fixedly connected to one end of the fixing rod, and the end of the first spring near the fixing rod is fixedly connected to one side of the fixing frame.

[0008] The effect achieved by the above components is that the fixing rod is pulled closer to the fixing frame by the first spring, thereby effectively confining the fixing rod inside the fixing hole.

[0009] Preferably, a second fixing strap is fixedly connected to one side of the connecting sleeve, and a Velcro closure is fixedly connected to the side of the second fixing strap away from the connecting sleeve, while a Velcro closure is fixedly connected to the other side of the connecting sleeve.

[0010] The effect achieved by the above components is to stick the Velcro tab and the Velcro mother tab together, which makes it easier to connect two adjacent connecting sleeves together.

[0011] Preferably, a fixing groove is provided on one side of the second fixing band, and a rubber plate is slidably connected to the inner wall of the fixing groove. One end of the rubber plate is fixedly connected to the same side of the connecting sleeve fixing the Velcro nut. A rotating rod is rotatably inserted through the end of the rubber plate away from the connecting sleeve, and a rotating frame is fixedly connected to both ends of the rotating rod.

[0012] The effect achieved by the above components is as follows: the rotating frame is manually controlled to drive the rotating rod to rotate, so that the rotating frame and the rubber plate are on the same horizontal plane, and then the rotating frame and the rubber plate are passed through the fixing groove. Then the rotating frame is manually controlled to drive the rotating rod to rotate, so that the rotating frame passing through the fixing groove is perpendicular to the rubber plate. In this way, the two connecting sleeves can be connected together by the second fixing belt.

[0013] Preferably, the fixing device includes a first connecting frame and a second connecting frame. The top of the first connecting frame is fixedly connected to the bottom of the connecting rope, and the bottom of the second connecting frame is fixedly connected to the top of the connecting strap. A positioning frame is slidably sleeved on one side of the first connecting frame and the second connecting frame. A rubber strip is fixedly connected to the inner wall of the positioning frame near the end of the first connecting frame.

[0014] The effect achieved by the above components is as follows: when using the fixing device, the first connecting frame and the second connecting frame are pressed tightly together, and the positioning frame is then fitted onto one side of the surface of the first connecting frame and the second connecting frame, and the rubber strip is squeezed into the inner wall of the first connecting frame. This makes it easy to fix the first connecting frame and the second connecting frame together. Reverse operation makes it easy to separate the first connecting frame and the second connecting frame, thus making it easy to replace the connecting strap or connecting rope.

[0015] Preferably, a first damping rod is fixedly connected to both sides of the second connecting frame. The end of the first damping rod away from the second connecting frame is fixedly connected to the inner wall of the positioning frame. A second spring is sleeved on the surface of the first damping rod. One end of the second spring is fixedly connected to one side of the second connecting frame. The end of the second spring near the first damping rod is fixedly connected to one side of the inner wall of the positioning frame.

[0016] The effect achieved by the above components is that the positioning frame is pulled towards the second connecting frame by the second spring, thereby restricting the positioning frame to the surface of the first connecting frame and the second connecting frame.

[0017] Preferably, the top of the first connecting frame is uniformly provided with rectangular grooves, the inner wall of the rectangular groove is slidably connected with a rectangular block, and the bottom of the rectangular block is fixedly connected to the top of the second connecting frame.

[0018] The effect achieved by the above components is to slide the rectangular block into the interior of the rectangular groove, so that the first connecting frame and the second connecting frame can be tightly attached together.

[0019] Preferably, a limiting block is slidably inserted through the top of the positioning frame, a second damping rod is fixedly connected to the top of the positioning frame, the top of the second damping rod is fixedly connected to one side of the limiting block, a third spring is sleeved on the surface of the second damping rod, one end of the third spring is fixedly connected to the top of the positioning frame, and the end of the third spring near the second damping rod is fixedly connected to the bottom of one side of the limiting block.

[0020] The effect achieved by the above components is that the limiting block is pulled towards the positioning frame by the third spring, so that the limiting block passes through the positioning frame, which makes it easier to restrict the positioning frame to the surface of the first connecting frame and the second connecting frame.

[0021] In this utility model, by setting a connecting device, when using the connecting device, the connecting sleeve is respectively placed on the surface of the tire through the connecting groove, and then the first fixing strap is wrapped around the side of the tire away from the connecting sleeve. Then the first fixing strap is inserted into the inside of the fixing frame, and the fixing rod is inserted into the inside of the fixing hole after passing through the fixing frame. In this way, one end of the first fixing strap can be restricted inside the fixing frame, which can conveniently restrict the connecting sleeve to the surface of the car tire.

[0027] Example 1, as Figure 1-4 As shown, a crane for loading and unloading vehicles at a dock has a connecting belt 4 at the bottom of a support frame 1, a connecting rope 2 at the top of the support frame 1, a hook 3 fixedly connected to the top of the connecting rope 2, a connecting sleeve 5 fixedly connected to the bottom of the connecting belt 4, a connecting device 6 on one side of the connecting sleeve 5, and a fixing device 7 on one side of the support frame 1. When using the crane, the hook 3 is hung on one end of the crane, and then the connecting sleeve 5 at the bottom of the connecting belt 4 is fitted onto the bottom of the vehicle wheel, so that the crane can transport vehicles at the dock.

[0028] Reference Figure 2 and Figure 3The connecting device 6 includes a first fixing band 602. A connecting groove 601 is provided on one side of the connecting sleeve 5. One side of the connecting sleeve 5 is fixedly connected to one end of the first fixing band 602. A fixing frame 603 is fixedly connected to the end of the connecting sleeve 5 away from the first fixing band 602. The inner wall of the fixing frame 603 is slidably connected to the first fixing band 602. A fixing hole 604 is provided on one side of the first fixing band 602. A fixing rod 605 is slidably inserted through one side of the fixing frame 603. The fixing rod 605 is slidably connected to the inner wall of the fixing hole 604. When using the connecting device 6, the connecting sleeve 5 is fitted onto the surface of the tire through the connecting groove 601, and then the first fixing band... 602 bypasses the tire on the side away from the connecting sleeve 5, and then inserts the first fixing strap 602 into the inside of the fixing frame 603. The fixing rod 605 passes through the fixing frame 603 and is then inserted into the fixing hole 604. This confines one end of the first fixing strap 602 inside the fixing frame 603, thus conveniently securing the connecting sleeve 5 to the surface of the car tire. A first spring 606 is fitted onto the surface of the fixing rod 605. One end of the first spring 606 is fixedly connected to one end of the fixing rod 605. The end of the first spring 606 near the fixing rod 605 is fixedly connected to one side of the fixing frame 603. The first spring 606 then moves towards the side of the fixing frame 604. Pulling the fixing rod 605 in direction 3 effectively confines it within the fixing hole 604. A second fixing strap 607 is fixedly connected to one side of the connecting sleeve 5, and a Velcro fastener 609 is fixedly connected to the side of the second fixing strap 607 away from the connecting sleeve 5. A Velcro fastener 608 is fixedly connected to one side of the other connecting sleeve 5. The Velcro fastener 609 and the Velcro fastener 608 are then glued together, facilitating the connection of two adjacent connecting sleeves 5. A fixing groove 613 is provided on one side of the second fixing strap 607, and a rubber plate 610 is slidably connected to the inner wall of the fixing groove 613. One end of the rubber plate 610 is attached to the connecting sleeve 5 with Velcro fastener. The same side of the female adhesive 608 is fixedly connected. The end of the rubber plate 610 away from the connecting sleeve 5 is rotatably inserted with a rotating rod 611. The two ends of the rotating rod 611 are fixedly connected with rotating frames 612. The rotating frame 612 is manually controlled to drive the surface of the rotating rod 611 to rotate, so that the rotating frame 612 and the rubber plate 610 are on the same horizontal plane. Then the rotating frame 612 and the rubber plate 610 are passed through the fixing groove 613. Then the rotating frame 612 is manually controlled to drive the rotating rod 611 to rotate, so that the rotating frame 612 passing through the fixing groove 613 is perpendicular to the rubber plate 610. In this way, the two connecting sleeves 5 can be connected together by the second fixing strap 607.

[0029] Reference Figure 4The fixing device 7 includes a first connecting frame 701 and a second connecting frame 702. The top of the first connecting frame 701 is fixedly connected to the bottom of the connecting rope 2, and the bottom of the second connecting frame 702 is fixedly connected to the top of the connecting strap 4. A positioning frame 707 is slidably fitted onto one side of the first connecting frame 701 and the second connecting frame 702. A rubber strip 708 is fixedly connected to the inner wall of the positioning frame 707 near the first connecting frame 701. When using the fixing device 7, the first connecting frame 701 and the second connecting frame 702 are pressed tightly together, and the positioning frame 707 is fitted onto the surface of one side of the first connecting frame 701 and the second connecting frame 702, and the rubber strip 708 is... The first connecting frame 701 is pressed into the inner wall of the second connecting frame 702, which facilitates fixing the first connecting frame 701 and the second connecting frame 702 together. Reversing the operation facilitates separating the first connecting frame 701 and the second connecting frame 702, thus facilitating the replacement of the connecting strap 4 or the connecting rope 2. First damping rods 705 are fixedly connected to both sides of the second connecting frame 702. The end of the first damping rod 705 away from the second connecting frame 702 is fixedly connected to the inner wall of the positioning frame 707. A second spring 706 is sleeved on the surface of the first damping rod 705. One end of the second spring 706 is fixedly connected to one side of the second connecting frame 702. The end of the second spring 706 near the first damping rod 705 and... One side of the inner wall of the positioning frame 707 is fixedly connected. A second spring 706 pulls the positioning frame 707 towards the second connecting frame 702, thereby restricting the positioning frame 707 to the surfaces of the first connecting frame 701 and the second connecting frame 702. Rectangular grooves 704 are evenly distributed on the top of the first connecting frame 701. A rectangular block 703 is slidably connected to the inner wall of the rectangular groove 704. The bottom of the rectangular block 703 is fixedly connected to the top of the second connecting frame 702. Sliding the rectangular block 703 into the rectangular groove 704 allows the first connecting frame 701 and the second connecting frame 702 to fit tightly together. A limiting block 7 is slidably inserted through the top of the positioning frame 707. 09. A second damping rod 710 is fixedly connected to the top of the positioning frame 707. The top of the second damping rod 710 is fixedly connected to one side of the limiting block 709. A third spring 711 is sleeved on the surface of the second damping rod 710. One end of the third spring 711 is fixedly connected to the top of the positioning frame 707. The end of the third spring 711 near the second damping rod 710 is fixedly connected to the bottom of one side of the limiting block 709. The limiting block 709 is pulled towards the positioning frame 707 by the third spring 711, so that the limiting block 709 passes through the positioning frame 707. This makes it easier to restrict the positioning frame 707 to the surface of the first connecting frame 701 and the second connecting frame 702.

[0030] Working principle: When using the crane, hook 3 is attached to one end of the crane, and then the connecting sleeve 5, located at the bottom of the connecting belt 4, is fitted onto the bottom of the car wheel. This allows the crane to transport vehicles on the dock. When using the connecting device 6, the connecting sleeve 5 is fitted onto the surface of the tire through the connecting groove 601. Then, the first fixing belt 602 is wrapped around the tire, away from the connecting sleeve 5, and inserted into the fixing frame 603. The fixing rod 605 is then inserted into the fixing hole 604 after passing through the fixing frame 603. The first spring 606 pulls the rod towards the fixing frame 603. Pull the fixing rod 605 to secure it within the fixing hole 604. This confines one end of the first fixing strap 602 within the fixing frame 603. Attach the Velcro tab 609 and the Velcro tab 608 together. Then, manually control the rotating frame 612 to rotate the surface of the rotating rod 611, bringing the rotating frame 612 and the rubber plate 610 to the same horizontal plane. Pass the rotating frame 612 and the rubber plate 610 through the fixing groove 613. Then, manually control the rotating frame 612 to rotate the rotating rod 611, bringing the rotating frame 612 through the fixing groove 613 and the rubber plate 610 to the same horizontal plane. 10 are perpendicular to each other, so that the two connecting sleeves 5 can be connected together by the second fixing strap 607. This makes it easy to connect two adjacent connecting sleeves 5 together, and can conveniently restrict the connecting sleeves 5 to the surface of the car tire. When using the fixing device 7, the rectangular block 703 is slid into the inside of the rectangular groove 704, so that the first connecting frame 701 and the second connecting frame 702 are tightly attached together. Then, the positioning frame 707 is fitted onto one side of the surface of the first connecting frame 701 and the second connecting frame 702. The positioning frame 707 is pulled towards the second connecting frame 702 by the second spring 706, thereby positioning... The frame 707 is confined to the surface of the first connecting frame 701 and the second connecting frame 702, and the rubber strip 708 is squeezed into the inner wall of the first connecting frame 701. The third spring 711 pulls the limiting block 709 towards the positioning frame 707, so that the limiting block 709 passes through the positioning frame 707. This makes it easy to confine the positioning frame 707 to the surface of the first connecting frame 701 and the second connecting frame 702, which makes it easy to fix the first connecting frame 701 and the second connecting frame 702 together. The reverse operation makes it easy to separate the first connecting frame 701 and the second connecting frame 702, which makes it easy to replace the connecting strap 4 or the connecting rope 2.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
