[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 7 This utility model provides a conveying device for entering and exiting a manhole, including a drive cylinder 3, a moving frame 1, a lifting frame 2, a transverse frame 5, and a receiving frame 4.

[0017] It should be understood that the drive cylinder 3 in this embodiment includes a pneumatic cylinder, a hydraulic cylinder or other linear drive cylinder, and the drive cylinder 3 in this embodiment can be implemented using products in the prior art, and its principle and structure will not be described in detail here.

[0018] The movable frame 1 is movable, and the drive cylinder 3 is disposed within the movable frame 1. It should be understood that the drive cylinder 3 can be connected to the base of the movable frame 1 via screw holes at its bottom (such as threaded connection) to ensure stability during lifting.

[0019] The lifting frame 2 is vertically mounted within the movable frame 1, and the telescopic rod of the drive cylinder 3 is connected to the lifting frame 2 so that the lifting frame 2 can be raised and lowered through the drive cylinder 3. That is to say, in this embodiment, the lifting frame 2 is mainly raised and lowered vertically within the movable frame 1 by the drive cylinder 3.

[0020] The horizontal moving frame 5 is slidably mounted on the lifting frame 2 in a horizontal direction. That is to say, the horizontal moving frame 5 can move along the left and right sides of the lifting frame 2.

[0021] The receiving frame 4 is used to store items (such as various maintenance tools and equipment), and the receiving frame 4 is height-adjustable at one end of the transverse frame 5. That is to say, the receiving frame 4 can be moved in and out of the manhole through the transverse frame 5, so as to push the items into and out of the manhole in the oil tank storage.

[0022] In the above manner, this utility model uses a receiving frame 4 to house various tools or equipment, and then uses a drive cylinder 3 to drive a horizontal moving frame 5 to rise and fall. The receiving frame 4 is then moved to a designated position by the horizontal moving frame 5, and finally the drive cylinder 3 is used to drive the horizontal moving frame 5 to rise and fall again. This allows tools or equipment to be moved in and out of the manhole without manual intervention, which can reduce equipment handling losses, reduce the labor intensity of handling personnel, effectively improve handling efficiency, and enhance safety.

[0023] Furthermore, the conveying device for entering and exiting the manhole also includes an adjusting mechanism 6, which is disposed at the other end of the transverse frame 5 and is used to drive the receiving frame 4 to rise and fall relative to the transverse frame 5. It should be understood that in this embodiment, the receiving frame 4 can be raised and lowered by using the drive cylinder 3 to drive the transverse frame 5, and the receiving frame 4 can also be raised and lowered relative to the transverse frame 5 by using the adjusting mechanism 6, so that the raising and lowering of the receiving frame 4 can be achieved in two ways.

[0024] In this embodiment, the movable frame 1 includes a supporting base plate 11, a first support rod 12, a second support rod 13, a third support rod 14, a fourth support rod 15, and a top structure 16. The supporting base plate 11 is rectangular in shape, and a plurality of casters 111 are spaced apart at the bottom of the supporting base plate 11 to enable the movable frame 1 to move. The first support rod 12, the second support rod 13, the third support rod 14, and the fourth support rod 15 are spaced apart at the four corners of the supporting base plate 11. The top structure 16 is located at the top of the first support rod 12, the top of the second support rod 13, the top of the third support rod 14, and the top of the fourth support rod 15.

[0025] It should be understood that the overall structure of the mobile frame 1 is a cuboid skeleton welded from metal square tubes, including a supporting base plate 11, a first support rod 12, a second support rod 13, a third support rod 14, a fourth support rod 15 and a top structure 16, which provides support strength and spatial structure for the entire transport device for entering and exiting a manhole.

[0026] Furthermore, the lifting frame 2 includes a first lifting rod 21, a first connecting rod 24, a second lifting rod 25, a second connecting rod 28, a first crossbar 29, and a second crossbar 210. One end of the first lifting rod 21 is slidably mounted on the first support rod 12 via a first roller structure 22, and the other end is slidably mounted on the second support rod 13 via a second roller structure 23. The first connecting rod 24 is connected to the first lifting rod 21. One end of the second lifting rod 25 is slidably mounted on the third support rod 14 via a third roller structure 26, and the other end is slidably mounted on the fourth support rod 15 via a fourth roller structure 27. The second connecting rod 28 is connected to the second lifting rod 25. The first crossbar 29 and the second crossbar 210 are spaced apart between the first connecting rod 24 and the second connecting rod 28. It should be understood that when the drive cylinder 3 performs lifting motion, it will drive the first connecting rod 24 and the second connecting rod 28 to lift together.

[0027] Specifically, the drive cylinder 3 includes a first drive cylinder 31 and a second drive cylinder 32. The first drive cylinder 31 is vertically fixed on the support base plate 11 between the first support rod 12 and the second support rod 13. The second drive cylinder 32 is vertically fixed on the support base plate 11 between the third support rod 14 and the fourth support rod 15. The telescopic rod of the first drive cylinder 31 is connected to the first lifting rod 21, and the telescopic rod of the second drive cylinder 32 is connected to the second lifting rod 25. It should be understood that the first drive cylinder 31 and the second drive cylinder 32 work synchronously, that is, the first drive cylinder 31 and the second drive cylinder 32 simultaneously act on the first lifting rod 21 and the second lifting rod 25 to make them move up and down.

[0028] In this embodiment, the first roller structure 22, the second roller structure 23, the third roller structure 26, and the fourth roller structure 27 each include a vertical drive rod 211, a first mounting bracket 212 disposed at one end of the vertical drive rod 211, and a second mounting bracket 213 disposed at the other end of the vertical drive rod 211. The first mounting bracket 212 is rotatably connected to a first roller 214, and the second mounting bracket 213 is rotatably connected to a second roller 215. Both the first roller 214 and the second roller 215 move up and down on the movable frame 1. That is, the first roller 214 and the second roller 215 of the first roller structure 22 slide along the first support rod 12; the first roller 214 and the second roller 215 of the second roller structure 23 slide along the second support rod 13; the first roller 214 and the second roller 215 of the third roller structure 26 slide along the third support rod 14; and the first roller 214 and the second roller 215 of the fourth roller structure 27 slide along the fourth support rod 15.

[0029] Furthermore, the conveying device for the manhole also includes a locking mechanism 7, which is used to lock the lifting frame 2 onto the movable frame 1.

[0030] Specifically, the locking mechanism 7 includes multiple chains 71 arranged vertically and multiple buckles 72. One end of each chain 71 is located on the top structure 16, and the other end is located on the supporting base plate 11. The first connecting rod 24 and the second connecting rod 28 are both connected to one end of the buckle 72 (i.e., both the first connecting rod 24 and the second connecting rod 28 are equipped with buckles 72). The other end of the buckle 72 is detachably connected to the chain 71 (e.g., the buckle 72 is equipped with a hook, which can hook onto a hole on the chain 71). In other words, the chains 71 are arranged along the entire height of the moving frame 1, and the buckles 72 can be fastened at different positions to position the lifting frame 2 in different positions, facilitating the stable lateral movement of the moving frame 5 on the lifting frame 2.

[0031] In this embodiment, the transverse frame 5 includes a first long bar 51 and a second long bar 52 spaced apart, and a plurality of fixed bars 53 spaced apart between the first long bar 51 and the second long bar 52. The first long bar 51 has a first groove 511 along its length, and its top surface has a first slot 512 communicating with the first groove 511. The second long bar 52 has a second groove 521 along its length, and its top surface has a second slot 522 communicating with the second groove 521. Both ends of the first crossbar 29 and the second crossbar 210 have a first slider 291 and a second slider 2101. The first slider 291 passes through the first slot 512 and is engaged and slidably disposed within the first groove 511, and the second slider 2101 passes through the second slot 522 and is engaged and slidably disposed within the second groove 521. It should be understood that the transverse frame 5 is slidably connected to the lifting frame 2 through the first slider 291 and the second slider 2101, so that the transverse frame 5 can move left and right.

[0032] It should be understood that the width of the first slider 291 is greater than the width of the first slot 512 and less than the width of the first slide groove 511, so that the first slider 291 is engaged within the first slide groove 511. Similarly, the width of the second slider 2101 is greater than the width of the second slot 522 and less than the width of the second slide groove 521, so that the second slider 2101 is engaged within the second slide groove 521. Furthermore, since the first slider 291 slides within the first slide groove 511 and the second slider 2101 slides within the second slide groove 521, both ends of the first and second slide grooves 511 are equipped with locking blocks to prevent the first slider 291 and the second slider 2101 from falling off.

[0033] In this embodiment, the adjustment mechanism 6 includes a support platform 61 and a hand-cranked winch 62. The support platform 61 is located at the other end of the first long bar 51 and the other end of the second long bar 52. The hand-cranked winch 62 is mounted on the support platform 61, and a first steel wire 63, a second steel wire 64, a third steel wire 65, and a fourth steel wire 66 are wound around the hand-cranked winch 62. It should be understood that in this embodiment, the extension lengths of the first steel wire 63, the second steel wire 64, the third steel wire 65, and the fourth steel wire 66 can be controlled by manually operating the hand-cranked winch 62. The hand-cranked winch 62 can be implemented using products from the prior art, and its principle and structure will not be described in detail here.

[0034] Specifically, one end of the first long bar 51 is provided with a first through hole (not shown) and a second through hole (not shown), and one end of the second long bar 52 is provided with a third through hole (not shown) and a fourth through hole (not shown). One end of the first steel wire 63 passes through the first through hole and is connected to the receiving frame 4; one end of the second steel wire 64 passes through the second through hole and is connected to the receiving frame 4; one end of the third steel wire 65 passes through the third through hole and is connected to the receiving frame 4; and one end of the fourth steel wire 66 passes through the fourth through hole and is connected to the receiving frame 4. In other words, the extension and retraction of the first steel wire 63, the second steel wire 64, the third steel wire 65, and the fourth steel wire 66 can be controlled by manually operating the hand-cranked winch 62, thereby controlling the lifting and lowering movement of the receiving frame 4 relative to the moving frame 5.

[0035] The specific work process is as follows: The receiving frame 4 is moved to the bottom surface of the transverse frame 5 (where the two are in contact) by adjusting mechanism 6, and the lifting frame 2 is lowered to its lowest point by controlling drive cylinder 3 (at which point the receiving frame 4 is outside the manhole). With the receiving frame 4 at its lowest position, tools or items are placed into the receiving frame 4. After loading, the lifting frame 2 is raised using drive cylinder 3, causing the receiving frame 4 and transverse frame 5 to rise. When the receiving frame 4 reaches the predetermined height (e.g., the receiving frame 4 and transverse frame 5 are aligned with the manhole), the transverse frame 5 is manually pushed relative to the lifting frame, so that... The receiving frame 4 passes through the manhole (i.e., enters the oil tank, at which point one end of the transverse frame 5 also passes through the manhole along with the receiving frame 4). Then, by controlling the drive cylinder 3 to work again, the lifting frame 2 is lowered. At the same time, the receiving frame 4 can be raised or lowered relative to the moving frame 5 by controlling the adjustment mechanism 6, so that the receiving frame 4 can be accurately moved to the bottom of the oil tank or a predetermined position inside the oil tank. Once the position is determined, the lifting frame 2 can be locked onto the moving frame 1 by the locking mechanism 7, which can prevent the receiving frame 4 from being raised or lowered, making it convenient for staff to move the items inside the receiving frame 4.

[0036] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
