Description

Technical Field

[0001] This utility model relates to the field of pipe fitting loading technology, and in particular to a pipe fitting ejector for loading. Background Technology

[0002] With economic development and urbanization, the demand for infrastructure construction is increasing, and the demand for pipeline systems is also increasing. As an important part of pipeline systems, the demand for pipe fittings is also rising. In the pipeline industry, it is often necessary to load a large number of pipe fittings onto transport vehicles.

[0003] Currently, common methods for loading pipe fittings have some shortcomings. For example, traditional manual loading is inefficient, labor-intensive, affects timely delivery and customer experience, and is prone to worker injuries. When using conventional equipment such as forklifts, it is difficult to precisely control the placement and arrangement of pipe fittings, often requiring further manual adjustments. Although this reduces labor intensity to some extent, loading efficiency remains unsatisfactory. Furthermore, pushing pipe fittings from the storage area to the vehicle compartment is inconvenient due to the lack of specialized pushing devices, easily leading to collisions and scratches between pipe fitting boxes, affecting the quality of the fittings. Utility Model Content

[0004] The purpose of this invention is to provide a pusher for loading pipe fittings onto vehicles, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A pipe fitting ejector for loading onto a vehicle is characterized by comprising a main beam, two columns symmetrically fixed above the main beam and extending vertically, and a number of fork arms fixed at intervals on the front side of the main beam. A drive mechanism is arranged on the two columns, and a push frame is provided above the fork arms. The drive mechanism is connected to the push frame, and the drive mechanism is used to drive the push frame to move back and forth to push the pipe fitting away from the vehicle body.

[0007] Preferably, the drive mechanism includes a pair of first traction arms, a pair of second traction arms, a U-shaped traction frame, a third traction arm, and a pair of drive devices. Each of the two columns has a drive device at its top. A first hinge rod is slidably mounted between the two columns. The drive device is used to drive the first hinge rod for lifting and lowering adjustment. A second hinge rod is mounted between the two columns near the main beam. One end of the U-shaped traction frame is hinged to the second hinge rod, and the other end is hinged to one end of the third traction arm. A first hinge seat is mounted on the push frame near the fork arm. The other end of the third traction arm is hinged to the first hinge seat. One end of each of the two first traction arms is hinged to the first hinge rod. The other ends of both first traction arms are each hinged to one end of each of the two second traction arms. A second hinge seat that can slide up and down is mounted on the push frame. The other ends of both second traction arms are hinged to the second hinge seat. The two first traction arms are each hinged to both sides of the U-shaped traction frame, and the two second traction arms are each hinged to both sides of the third traction arm.

[0008] Preferably, the driving device is a hydraulic cylinder, with two hydraulic cylinders vertically fixed to the top of the corresponding column, and the ends of the telescopic rods are fixedly connected to the first hinge rod.

[0009] Preferably, the push frame consists of a bottom beam, a top beam, and several uprights. The top beam is arranged above the bottom beam, and several uprights are fixed between the bottom beam and the top beam at intervals and all extend vertically. A sliding rod is also vertically fixed between the bottom beam and the top beam, and the second hinge seat is slidably fitted onto the sliding rod.

[0010] Preferably, the bottom of the bottom beam is provided with several mounting slots at intervals, and each mounting slot is rotatably installed with a guide wheel, and each guide wheel is supported and abutted against the top of the fork arm.

[0011] Preferably, a connecting arm is fixedly connected between the tops of the two columns.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) This utility model is designed and configured with a special pipe loading and pushing device on the existing pallet truck. The special pallet is prepared in advance. When loading, the drive mechanism is used to push the pusher forward, which can directly push the pipe products prepared on the special pallet into the truck. The pipe loading is basically completed in one step without the need for subsequent manual processing, which effectively improves the loading efficiency. Moreover, the pipe will not be damaged during the pushing process, and the pipes will not collide with each other, which effectively ensures the quality of the pipes.

[0014] (2) This utility model uses several uprights as the main pushing support components, which are arranged at intervals between the bottom beam and the top beam. There are gaps between adjacent uprights, which is conducive to the driver observing the specific situation in front of the push frame and avoids completely obstructing the driver's view. The structure layout is reasonable.

[0015] (3) The present invention utilizes several guide wheels at the bottom of the push frame to support and abut against each fork arm, which can provide effective support for the entire push frame and ensure the overall stability of the push frame. In addition, during the forward and backward movement of the push frame, the guide wheels roll against the fork arm, reducing the friction between the push frame and the fork arm, and ensuring that the push frame movement adjustment process is easy and smooth enough.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a pipe fitting ejector for loading onto a vehicle includes a main beam 1, a mounting bracket 11, a fork arm 2, a column 3, a connecting arm 31, a drive mechanism 4, a first hinge rod 41, a second hinge rod 42, a first hinge seat 43, a second hinge seat 44, a first traction arm 45, a second traction arm 46, a U-shaped traction frame 47, a third traction arm 48, a drive device 49, a pusher 5, a bottom beam 51, a mounting groove 511, a guide wheel 512, a column 52, a top beam 53, and a slide bar 54.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 4 As shown, two uprights 3 are symmetrically fixed above the main beam 1 and extend vertically. Several fork arms 2 are fixed at intervals on the front side of the main beam 1. The main beam 1 is mounted on the lifting frame on the front side of the forklift via the mounting bracket 11 arranged on it. The forklift can drive the main beam 1 to move up and down, so that the special pallet containing pipe fittings can be lifted when loading. There are multiple fork arms 2 arranged on the front side of the main beam 1, which form a widened design with the main beam 1, which can lift and transfer more pipe fitting products at one time and improve loading efficiency.

[0025] A drive mechanism 4 is arranged on the two uprights 3, and a pusher 5 is provided above the fork arm 2. The drive mechanism 4 is connected to the pusher 5. The drive mechanism 4 is used to drive the pusher 5 to move back and forth to push the pipes away into the truck bed. The forklift moves forward to drive the fork arm 2 to move forward and insert it into the special pallet containing the pipes. The forklift lifts the stacked pipe products to the required height, and then moves the pipes into the truck bed. Then, the drive mechanism 4 works to push the pusher 5 forward to push the pipes away into the truck bed, completing the loading of the pipes. Then, the drive mechanism 4 works to drive the pusher 5 to retract and reset, so as to facilitate the next transfer.

[0026] This utility model designs and configures a special pipe fitting loading and pushing device on existing pallet trucks. It uses a special pallet to prepare the goods in advance. During loading, the drive mechanism 4 pushes the pusher 5 forward, which can directly push the pipe fitting products prepared on the special pallet into the truck. The pipe fittings can be loaded in one step without the need for subsequent manual processing, which effectively improves the loading efficiency. Moreover, the pipe fittings will not be damaged during the pushing process, and the pipe fittings will not collide with each other, which effectively ensures the quality of the pipe fittings.

[0027] In addition, it is worth noting that in practical applications, visual displays and cameras can be installed at the appropriate locations to improve the blind spots for workers. At the same time, adding markings on the ground can guide drivers to park, thus enhancing safety.

[0028] The drive mechanism 4 includes a pair of first traction arms 45, a pair of second traction arms 46, a U-shaped traction frame 47, a third traction arm 48, and a pair of drive devices 49. Drive devices 49 are installed on the top of each of the two columns 3. A first hinge rod 41 is slidably installed between the two columns 3. The drive devices 49 are used to drive the first hinge rod 41 for lifting and lowering adjustment. A second hinge rod 42 is installed between the two columns 3 near the main beam 1. One end of the U-shaped traction frame 47 is hinged to the second hinge rod 42, and the other end is hinged to one end of the third traction arm 48. A pusher 5 is installed near the fork arm 2. There is a first hinge seat 43, and the other end of the third traction arm 48 is hinged to the first hinge seat 43. One end of each of the two first traction arms 45 is hinged to the first hinge rod 41. The other end of each of the two first traction arms 45 is hinged to one end of each of the two second traction arms 46. A second hinge seat 44 that can slide up and down is installed on the push frame 5. The other end of each of the two second traction arms 46 is hinged to the second hinge seat 44. The two first traction arms 45 are hinged to both sides of the U-shaped traction frame 47. The two second traction arms 46 are hinged to both sides of the third traction arm 48.

[0029] The drive device 49 uses hydraulic cylinders. Two hydraulic cylinders are vertically fixed on the top of the corresponding column 3, and the ends of the telescopic rods are fixedly connected to the first hinge rod 41.

[0030] When the drive device 49 extends, it pushes the first hinge rod 41 downward, causing the first traction arm 45 to swing. Under the hinged traction of the first traction arm 45 and the second traction arm 46, the U-shaped traction frame 47 and the third traction arm 48, the second traction arm 46 and the third traction arm 48, the second traction arm 46 and the push frame 5, and the third traction arm 48 and the push frame 5, the push frame 5 can be driven to move forward, thus realizing the function of moving the propellant. When the drive device 49 retracts, under the corresponding hinged traction, the push frame 5 can be driven to retract.

[0031] The U-shaped traction frame 47 has a U-shaped design with a gap in the middle. When the push frame 5 is driven back to the limit position, it is used to accommodate the third traction arm 48, so as to avoid the U-shaped traction frame 47 and the third traction arm 48 from blocking or interfering with each other. The structural layout is reasonable.

[0032] In addition, the drive unit 49 can also be a linear drive component such as a cylinder or a hydraulic cylinder.

[0033] Specifically, the push frame 5 consists of a bottom beam 51, a top beam 53 and several uprights 52. The top beam 53 is arranged above the bottom beam 51. Several uprights 52 are fixed between the bottom beam 51 and the top beam 53 at intervals and all extend vertically. A sliding rod 54 is also vertically fixed between the bottom beam 51 and the top beam 53. The second hinge seat 44 is slidably fitted on the sliding rod 54.

[0034] Several uprights 52 serve as the main pushing support components, and are arranged at intervals between the bottom beam 51 and the top beam 53. There are gaps between adjacent uprights 52, which helps the driver to observe the specific situation in front of the push frame 5 and avoids completely obstructing the driver's view. The structural layout is reasonable.

[0035] The bottom beam 51 has several mounting slots 511 spaced apart at its bottom. Each mounting slot 511 has a guide wheel 512 rotatably mounted in it. Each guide wheel 512 supports and abuts against the upper part of the fork arm 2. The bottom of the push frame 5 is supported and abuts against each fork arm 2 by several guide wheels 512, which can provide effective support for the entire push frame 5 and ensure the overall stability of the push frame 5. In addition, during the back-and-forth movement of the push frame 5, the guide wheels 512 roll against the fork arm 2, reducing the friction between the push frame 5 and the fork arm 2, and ensuring that the movement and adjustment of the push frame 5 is easy and smooth enough.

[0036] A connecting arm 31 is fixedly connected between the tops of the two columns 3, and the connecting arm 31 is used to connect the two columns 3, which further strengthens the two columns 3.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Therefore, any modifications, equivalent changes, or improvements made in accordance with the claims of this utility model shall still fall within the scope of this utility model.
