Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil receiving and dispatching technology, specifically to an oil pipe winding device. Background Technology
[0002] Currently, most refined oil products are transported and transferred via railway tank cars. Existing technologies typically use receiving and dispatching cars for emergency reception of oil arriving by rail and emergency dispatching of oil to railway tank cars; and when fixed facilities and equipment such as pump houses and railway trestle bridges are damaged or cannot meet the needs of large-scale supply, temporary railway tank car receiving and dispatching points are set up to realize the rapid receiving and dispatching function of oil from railway tank cars.
[0003] Oil delivery trucks typically require oil hoses to transport refined oil. Existing oil hoses are polyurethane flat hoses, 150 mm in diameter, 24 meters in length per hose, and weigh approximately 2.5 kg / m. A single 24-m oil hose weighs approximately 60 kg.
[0004] Multiple oil hoses need to be transported by the oil receiving and dispatching vehicle. Due to the limited internal space of the vehicle, the hoses need to be wound up and stored. During oil receiving and dispatching operations, the hoses are wound manually. Typically, the user must manually press the hose against the winding device and rotate the device to wind the hose around once, until the next hose is wrapped around the first turn. The user can only release their grip after this process. Until then, the user needs to maintain a firm grip on the hose, which is labor-intensive, time-consuming, inefficient, and has a slow winding response. Utility Model Content
[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides an oil hose reel device to solve the problems of high labor intensity and slow reeling response speed caused by the need for users to continuously apply force to tighten the oil hose.
[0006] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:
[0007] This utility model provides an oil pipe winding device, including a first protective wall, a second protective wall, a winding unit, and a clamping unit. The winding unit is disposed between the first protective wall and the second protective wall, and the clamping unit is disposed on the winding unit. The clamping unit is used to clamp the oil pipe, and the winding unit is used to wind up the oil pipe.
[0008] The winding unit includes multiple crossbars, the two ends of which are respectively connected to the first retaining wall and the second retaining wall;
[0009] The clamping unit includes a fixed clamp, a movable clamp, and a sliding frame. The fixed clamp and the sliding frame are both mounted on the crossbar, and the movable clamp is mounted on the sliding frame. The movable clamp can slide on the sliding frame and can form a clamping ring with the fixed clamp to clamp the rigid pipe section of the oil pipe. The inner diameter of the clamping ring is smaller than the outer diameter of the pipe clamp, preventing the rigid pipe section from detaching from the clamping ring.
[0010] Furthermore, the clamping unit also includes a limiting plate, the two ends of which are respectively connected to two adjacent crossbars.
[0011] Furthermore, the clamping unit also includes a return spring, one end of which is connected to the movable card seat, and the other end of which is connected to the limiting plate. The return spring is used to push the movable card seat towards the fixed card seat.
[0012] Furthermore, the fixing bracket is provided with a snap-fit hole, the direction of which is perpendicular to the fixing bracket.
[0013] Furthermore, the snap-fit hole is a tapered through hole, with one end of the snap-fit hole facing the movable card holder being the snap-fit end and the other end being the insertion end.
[0014] Furthermore, the inner diameter of the snap-fit end is greater than or equal to the outer diameter of the clamp, and less than the inner diameter of the insertion end.
[0015] Furthermore, the movable bracket is provided with a bevel, and when a rigid pipe section is inserted into the clamping hole, the pipe clamp can connect with the bevel and push the movable bracket away from the fixed bracket.
[0016] Furthermore, the clamping unit also includes a pull rod, one end of which is connected to the movable card seat, and the other end of which is a free end, and the pull rod can pass through the first protective wall.
[0017] Furthermore, the two ends of the fixed bracket are respectively connected to two adjacent crossbars.
[0018] Furthermore, two sliding frames are provided, and they are respectively arranged on two adjacent crossbars. The two sliding frames are used to connect to both ends of the movable card seat.
[0019] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:
[0020] (1) The movable card seat of this utility model can slide on the sliding frame and can form a clamping ring with the fixed card seat to clamp the hard pipe section together. The inner diameter of the clamping ring is smaller than the outer diameter of the pipe clamp to prevent the hard pipe section from falling off the clamping ring. The user only needs to clamp the hard pipe section with the clamping ring to fix the oil pipe on the winding unit. There is no need to keep pressing the hard pipe section with force. The labor intensity is low and the winding response speed is fast.
[0021] (2) The reset spring of this utility model is used to push the movable card seat in the direction of the fixed card seat to ensure that the clamping ring formed by the movable card seat and the fixed card seat keeps clamping the hard pipe section and prevents the hard pipe section from falling out of the clamping ring.
[0022] (3) The user only needs to roughly align the rigid pipe section with the insertion end of the snap-fit hole of this utility model. The pipe clamp can push the movable snap-fit seat away from the fixed snap-fit seat, and the rigid pipe section can be quickly inserted into the clamping ring. The movable snap-fit seat can automatically clamp the rigid pipe section. The clamping operation is simple and fast.
[0023] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

[0030] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.
[0031] A specific embodiment of this utility model is as follows: Figure 1 As shown, an oil pipe winding device includes a first protective wall 1, a second protective wall 2, a winding unit 3, and a clamping unit 4. The winding unit 3 is disposed between the first protective wall 1 and the second protective wall 2, and the clamping unit 4 is disposed on the winding unit 3. The clamping unit 4 is used to clamp the oil pipe 5, and the winding unit 3 is used to wind up the oil pipe 5.
[0032] Preferably, the first guard wall 1 and the second guard wall 2 have the same structure. The first guard wall 1 is a circular plate, or the first guard wall 1 is a wheel with spokes. The first guard wall 1 and the second guard wall 2 are used to prevent the oil pipe 5 from axially disengaging from the winding unit 3.
[0033] Preferred, such as Figure 2 and Figure 3 As shown, the winding unit 3 includes multiple crossbars 31, with both ends of each crossbar 31 connected to the first protective wall 1 and the second protective wall 2, respectively. The crossbars 31 are evenly distributed circumferentially around the center of the first and second protective walls 1 and 2. The oil pipe 5 includes a rigid pipe section 51 and a flexible pipe section 52. The rigid pipe section 51 is cylindrical and located at the end of the flexible pipe section 52. When winding the oil pipe 5, the user typically needs to manually press the rigid pipe section 51 against the crossbars 31 and rotate the first protective wall 1 or the second protective wall 2 to connect the flexible pipe section 52 sequentially to all the crossbars 31. The flexible pipe section 52 is then wound around the winding unit 3 once until the next flexible pipe section 52 presses down on the first turn of the flexible pipe section 52 before the user can release their grip. Before this, the user needs to maintain a firm grip on the rigid pipe section 51, resulting in high labor intensity and a long operation time.
[0034] Preferred, such as Figure 3 and Figure 4As shown, the oil pipe 5 also includes a pipe clamp 53, which is located at the end of the rigid pipe section 51. The outer diameter of the pipe clamp 53 is larger than the outer diameter of the rigid pipe section 51. The clamping unit 4 includes a fixed clamp 41, a movable clamp 42, and a sliding frame 43. The fixed clamp 41 and the sliding frame 43 are both mounted on the crossbar 31, and the movable clamp 42 is mounted on the sliding frame 43. The movable clamp 42 can slide on the sliding frame 43 and can form a clamping ring with the fixed clamp 41 to clamp the rigid pipe section 51. The inner diameter of the clamping ring is smaller than the outer diameter of the pipe clamp 53 to prevent the rigid pipe section 51 from detaching from the clamping ring. The user only needs to clamp the rigid pipe section 51 with the clamping ring to fix the oil pipe 5 on the winding unit 3. It is not necessary to keep pressing the rigid pipe section 51 with force, which reduces labor intensity and operation time.
[0035] Preferably, the two ends of the fixed bracket 41 are respectively connected to two adjacent crossbars 31 to increase the connection strength between the clamping unit 4 and the winding unit 3, thereby enhancing the durability of the tubing winding device in this embodiment. Two sliding frames 43 are provided, and are respectively set on two adjacent crossbars 31. The two sliding frames 43 are used to connect to the two ends of the movable bracket 42 to further prevent the movable bracket 42 from detaching from the fixed bracket 41.
[0036] Preferably, in order to simplify the operation procedure and enable the clamping ring to automatically clamp the rigid pipe segment 51, the clamping unit 4 in this embodiment further includes a limiting plate 44 and a return spring 45. The two ends of the limiting plate 44 are respectively connected to two adjacent crossbars 31. One end of the return spring 45 is connected to the movable card seat 42, and the other end of the return spring 45 is connected to the limiting plate 44. The return spring 45 is used to push the movable card seat 42 towards the fixed card seat 41 to ensure that the clamping ring formed by the movable card seat 42 and the fixed card seat 41 maintains clamping on the rigid pipe segment 51 and prevents the rigid pipe segment 51 from detaching from the clamping ring.
[0037] Preferred, such as Figure 4As shown, to enable the rigid pipe section 51 to be quickly inserted into the clamping sleeve, the fixed clamping seat 41 is provided with a snap-fit hole, the direction of which is perpendicular to the fixed clamping seat 41. The snap-fit hole is a tapered through hole, with the end facing the movable clamping seat 42 being the snap-fit end and the other end being the insertion end. The inner diameter of the snap-fit end is greater than or equal to the outer diameter of the pipe clamp 53 and less than the inner diameter of the insertion end. By roughly aligning the rigid pipe section 51 with the insertion end, the rigid pipe section 51 can be quickly inserted into the clamping sleeve. The movable clamping seat 42 is provided with a bevel. After the rigid pipe section 51 is inserted into the snap-fit hole, the pipe clamp 53 can connect with the bevel and push the movable clamping seat 42 away from the fixed clamping seat 41, causing the clamping sleeve to open. Continue inserting the rigid pipe section 51 into the clamping sleeve until the pipe clamp 53 passes the bevel. Under the push of the return spring 45, the movable clamping seat 42 moves towards the fixed clamping seat 41, closing the clamping sleeve. The user only needs to roughly align the rigid pipe section 51 with the insertion end of the clamping hole, and the pipe clamp 53 can push the movable clamping seat 42 away from the fixed clamping seat 41. The rigid pipe section 51 can be quickly inserted into the clamping sleeve, and the movable clamping seat 42 can automatically clamp the rigid pipe section 51. The clamping operation is simple and quick.
[0038] Preferred, such as Figure 3 and Figure 4 As shown, in order to quickly detach the oil pipe 5 from the clamping unit 4 during the laying of the oil pipeline, the clamping unit 4 in this embodiment also includes a pull rod 46. One end of the pull rod 46 is connected to the movable bracket 42, and the other end of the pull rod 46 is a free end, which can pass through the first protective wall 1. When the user pulls the free end of the pull rod 46 away from the fixed bracket 41, the movable bracket 42 can be disengaged from the fixed bracket 41. When the user pulls the oil pipe 5 towards the insertion end, the pipe clamp 53 can be disengaged from the clamping ring, thus completing the quick detachment of the oil pipe 5 from the clamping unit 4.
[0039] Preferably, the hose reel device of this embodiment can be installed on a receiving and dispatching vehicle and driven by the vehicle's engine power, saving manpower.
[0040] Compared with the existing technology where users need to keep pressing the rigid pipe section 51 with force, which is labor-intensive and takes a long time, the movable bracket 42 can slide on the sliding frame 43 and can form a clamping ring with the fixed bracket 41 to clamp the rigid pipe section 51 together. The inner diameter of the clamping ring is smaller than the outer diameter of the pipe clamp 53 to prevent the rigid pipe section 51 from falling out of the clamping ring. The user only needs to clamp the rigid pipe section 51 with the clamping ring to fix the oil pipe 5 on the winding unit 3. There is no need to keep pressing the rigid pipe section 51 with force, which reduces labor intensity and operation time. The other end of the return spring 45 is connected to the limit plate 44. The return spring 45 is used to push the movable bracket 42 towards the fixed bracket 41 to ensure that the clamping ring formed by the movable bracket 42 and the fixed bracket 41 keeps clamping the rigid pipe section 51 and prevents the rigid pipe section 51 from falling out of the clamping ring. The user only needs to roughly align the rigid pipe section 51 with the insertion end of the snap-fit hole. The pipe clamp 53 can push the movable bracket 42 away from the fixed bracket 41, and the rigid pipe section 51 can be quickly inserted into the clamping ring. The movable bracket 42 can automatically clamp the rigid pipe section 51. The clamping operation is simple and fast.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
