Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe transfer equipment, and in particular to a steel pipe transfer vehicle for steel structure building construction and a use method thereof. Background Art

[0002] The steel pipe transfer vehicle for steel structure construction is a construction equipment designed for the transportation and transfer of steel pipes. It is widely used in construction sites due to its strong structure, strong load-bearing capacity, strong adaptability, easy operation, high safety, improved work efficiency and strong customizability. It is especially suitable for steel structure construction sites that need to carry and transfer a large number of steel pipes. It is more suitable for the internal cooperation of cranes in workshops to transport heavy objects across spans, as well as in machine manufacturing and metallurgical factories.

[0059] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0061] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0062] This embodiment provides a steel pipe transfer vehicle for steel structure construction. Figure 1-2 As shown, it includes a vehicle body 1, a pipe bracket 2 for supporting steel pipes, a pipe pressing plate 3 for pressing the steel pipes supported by the pipe bracket 2, a stabilizing plate 4 for improving the static stability of the vehicle body 1, and a pipe pushing plate 5 for pushing the steel pipes. Among them, the vehicle body 1 has an open side 1-1, and the pipe bracket 2 is movably constructed on the vehicle body 1. The length of the side end extending out of the open side 1-1 is adjustable, so that the steel pipes of different lengths can be stably supported and carried without additionally tying a fixing belt. The pipe pressing plate 3 is movably constructed on the vehicle body 1, and it is located above the pipe bracket 2. The distance between the bottom end and the pipe bracket 2 is adjustable, so that the steel pipes on the pipe bracket 2 can be pressed or loosened. The stabilizing plate 4 is movably constructed under the vehicle body 1. When the vehicle body 1 stops moving and is ready to unload the pipe, the stabilizing plate 4 presses against the ground under the vehicle body 1 to increase the friction and prevent the vehicle body 1 from moving unplanned. The pipe push plate 5 is movably constructed on the vehicle body 1 and is located on the side of the pipe bracket 2 away from the open side 1-1. It can move toward the pipe bracket 2 to push the steel pipe on the pipe bracket 2 toward the open side 1-1 to assist in unloading the pipe and improve efficiency.

[0063] In this embodiment, the vehicle body 1 includes at least a base plate 1-2, a side plate 1-3, a damping rod 1-4 and a running wheel 1-5. The base plate 1-2 can be configured into a square, circular or other shape. All configurations that can meet the installation requirements of the above-mentioned structures are within the protection scope of this case. To facilitate the display and explanation of the content of the solution, this embodiment is explained by taking a square bottom plate 1-2 as an example. Three side plates 1-3 are provided, which are sequentially arranged around three adjacent side ends of the bottom plate 1-2. The three side plates 1-3 are connected to form a C-shaped structure in a top view, and the open side of the C-shape corresponds to the open side 1-1 of the vehicle body 1; the top of the side plate 1-3 may or may not be provided with a top plate, and no specific restriction is made here; a number of damping rods 1-4 are provided, which are evenly distributed under the bottom plate 1-2 and fixedly connected to the bottom plate 1-2. The damping rods 1-4 serve as legs of the vehicle body 1 to support the vehicle body 1 and provide installation sites for the running wheels 1-5. The running wheels 1-5 are installed at the bottom of the damping rods 1-4 to facilitate the movement of the vehicle body 1; in addition, due to the large dead weight and inertia of the steel pipe, the damping rods 1-4 can also reduce bumps during the transfer of the steel pipe, avoiding excessive vibration and displacement of the steel pipe, thereby causing troubles or safety accidents of varying degrees. The traveling wheels 1-5 can be mechanical wheels with locking mechanisms or electric wheels with braking mechanisms, which can independently maintain the static stability of the vehicle body 1 to a certain extent. However, when excessive relative vibration, friction, etc. occur between the steel pipe and the vehicle body 1 during pipe unloading, the stabilizing plate 4 is required to improve the static stability of the vehicle body 1.

[0064] The pipe bracket 2 is in the shape of a flat plate and is placed on the top surface of the base plate 1-2. A plurality of arc-shaped pipe bracket grooves 2-1 parallel to each other are provided on the top of the pipe bracket 2 to fit the side walls of the supported steel pipe to prevent the steel pipe from rolling. In order to improve the transfer vehicle's ability to transfer large-size steel pipes, the present embodiment sets the open side 1-1 at the long end of the base plate 1-2, and extends the arc-shaped pipe bracket grooves 2-1 along the length direction of the base plate 1-2 to increase the total length adjustment range of the vehicle body 1 and the pipe bracket 2 to meet the transfer requirements of steel pipes of different lengths.

[0065] In order to prevent the pipe bracket 2 from slipping off the vehicle body 1 and to improve the efficiency and accuracy of adjusting the position of the pipe bracket 2, a driving mechanism 6 and a moving member 7 are provided on the vehicle body 1 in this embodiment (see attached Figure 3-5), the driving mechanism 6 is fixedly arranged on the vehicle body 1 (referring only to the inactive parts of the driving structure, such as the housing, the mounting frame, etc., which are fixedly installed on the vehicle body 1, while the structural parts of the driving mechanism 6 that implement rotation, extension, etc. can move flexibly), the moving part 7 is slidably arranged on the vehicle body 1, and is driven by the driving mechanism 6 to approach or move away from the open side 1-1, and the pipe bracket 2 and the moving part 7 are fixedly connected. The pipe bracket 2 is limited by the connection between the driving mechanism 6 and the moving part 7 and the vehicle body 1 to prevent it from slipping, and the position of the pipe bracket 2 on the vehicle body 1 is changed by the power transmission and displacement transmission of the driving mechanism 6 and the moving part 7, so as to adjust the total length of the pipe bracket 2 and the vehicle body 1.

[0066] Specifically, in order to improve the connection and sliding stability, a slide groove-slider connection method can be adopted between the above-mentioned moving part 7 and the vehicle body 1, and the moving part 7 is constructed to be at least partially slidably embedded in the vehicle body 1. By surrounding the moving part 7 by the vehicle body 1, the tightness of the connection between the moving part 7 and the vehicle body 1 is improved, thereby improving the tightness of the connection between the pipe bracket 2 and the vehicle body 1.

[0067] The moving member 7 and the driving mechanism 6 can be constructed on the bottom plate 1-2 or the side plate 1-3 of the vehicle body 1 as needed. In order to avoid interference with other structures on the vehicle body 1, the moving member 7 and the driving mechanism 6 are constructed on the bottom plate 1-2 of the vehicle body 1 in this embodiment, and an installation cavity 1-21 is set in the bottom plate 1-2 (or an installation groove is set on the top surface of the bottom plate 1-2) for installing the driving mechanism 6. A moving member slide groove 1-22 is set on the top surface of the bottom plate 1-2, and the moving member slide groove 1-22 is connected to the installation cavity 1-21 (or the installation groove). The moving member 7 is at least partially slidably constructed in the moving member slide groove 1-22, and the moving member 7 is connected to the driving mechanism 6 so that the moving member 7 moves along the length direction of the moving member slide groove 1-22 under the drive of the driving mechanism 6. As for the construction direction of the moving part slide 1-22, it can be configured according to actual needs, as long as the projection of the sliding path of the moving part 7 in the length direction of the base plate 1-2 meets the requirement of the moving length of the pipe bracket 2, that is: the length direction of the moving part slide 1-2 can be parallel to the length direction of the base plate 1-2, or it can be non-parallel, but it cannot be parallel to the width direction of the base plate 1-2. In order to briefly explain the scheme, the following continues to explain this embodiment based on the scheme that the length direction of the moving part slide 1-2 is parallel to the length direction of the base plate 1-2.

[0068] Specifically, the driving mechanism 6 at least includes a driver 6-1 and a movable rod 6-2. The movable rod 6-2 is connected to the output end of the driver 6-1 and is driven by the driver 6-1 to move along its own length direction or rotate around its own axis. When the driver 6-1 uses an electric telescopic rod, a telescopic cylinder, a hydraulic rod or other device with a linear telescopic function, the movable rod 6-2 is arranged at the output end of the driver 6-1, and the movable member 7 is fixed to the other end of the movable rod 6-2. The movable rod 6-2 moves along its own length direction with the action of the output end of the driver 6-1, and drives the movable member 7 to slide on the vehicle body 1; when the driver 6-1 uses a device that can output a rotational torque (such as a stepping motor, a servo motor 16 or a manual turntable), the movable rod 6-2 is arranged at the output end of the driver 6-1, and the movable member 7 is constructed according to the selection of the movable rod 6-2. The movable member 7 is threadedly or meshedly connected to the movable rod 6-2. When the movable rod 6-2 rotates around its own axis with the action of the output end of the driver 6-1, the movable member 7 is driven to move along the length direction of the movable rod 6-2 through threaded or meshing transmission. The above-mentioned configuration methods of each driving mechanism 6 can achieve the purpose of driving the movable member 7 and the pipe bracket 2 to move.

[0069] When the driver 6-1 is a device capable of outputting rotational torque and the movable rod 6-2 is a threaded rod, an internal threaded through hole adapted to the thread on the movable rod 6-2 is opened in the movable member 7, and the movable member 7 is sleeved on the movable rod 6-2; when the driver 6-1 is a device capable of outputting rotational torque and the movable rod 6-2 is a worm gear, a rack 8 extending in the same direction as the movable member slide groove 1-22 can be set on the bottom surface of the movable member 7, a worm gear 9 is meshed and connected to the outer side of the movable rod 6-2, and a transmission gear 10 is meshed and connected to the bottom of the movable member 7, the worm gear 9 and the transmission gear 10 are coaxially fixedly connected, and their rotating shafts are rotatably set in the base plate 1-2, when the movable rod 6-2 rotates, the worm gear 9 and the transmission gear 10 are driven to rotate synchronously, and the rack 8 on the bottom surface of the movable member 7 moves along the movable member slide groove 1-22 under the action of the transmission gear 10, thereby realizing the position adjustment of the movable member 7 and the pipe bracket 2.

[0070] Reference Figure 6-8The inner side wall of the vehicle body 1 is provided with at least two groups of tube clamping plate chutes 1-31, the end of the tube clamping plate 3 is slidably connected with the tube clamping plate chutes 1-31, and the end of the tube clamping plate 3 is at least partially slidably embedded in the tube clamping plate chutes 1-31. The inner wall of the tube clamping plate chutes 1-31 is used to limit the end of the tube clamping plate 3, thereby improving the sliding stability; when the tube clamping plate 3 slides inside, it can approach the tube bracket 2, limit the steel pipe supported on the tube bracket 2, and improve the stability of the steel pipe during the transfer process. At least two groups of tube clamping plate chutes 1-31 can be set on the same side plate 1-3, or on different side plates 1-3, and are preferably set on a group of opposite side plates 1-3, so as to limit a group of opposite sides of the tube clamping plate 3, thereby maximally improving the connection stability and sliding stability. Of course, the area of ​​the tube pressing plate 3 itself is relatively large, and a slider 11 compatible with the tube pressing plate slide groove 1-31 can be set at the end of the tube pressing plate 3 to facilitate the construction and use of the transfer vehicle; an extension rod 23 (or extension plate) can also be set on the side of the tube pressing plate 3 to facilitate manual operation, and force can be applied to the extension rod 23 to press down or lift the tube pressing plate 3, thereby improving the convenience of using the transfer vehicle.

[0071] As for the construction direction of the tube pressure plate slide 1-31, it can be configured according to actual needs, as long as the projection of the sliding path of the tube pressure plate 3 in the height direction of the side plate 1-3 meets the requirement of the moving length of the tube pressure plate 3, that is: the length direction of the tube pressure plate slide 1-31 can be parallel to the height direction of the side plate 1-3, or it can be non-parallel, but the tube pressure plate slide 1-31 cannot extend horizontally. For the sake of concise explanation of the scheme, the following continues to explain this embodiment based on the scheme that the length direction of the tube pressure plate slide 1-31 is parallel to the height direction of the side plate 1-3.

[0072] Specifically, in order to improve the limiting effect of the tube pressing plate 3 on the steel pipe, in addition to using the tube pressing plate 3 for pressing by its own weight, ratchets 12 distributed along its length direction can be set in at least one group of tube pressing plate slide grooves 1-31, and a pawl 13 is rotatably connected to the side end of the tube pressing plate 3 close to the ratchet 12 (if the end of the tube pressing plate 3 is provided with a slider 11 adapted to the tube pressing plate slide groove 1-31, a pawl 13 is set on the slider 11), and a reset spring 14 is set between the pawl 13 and the end of the tube pressing plate 3, and the reset spring 14 presses the pawl 13 and the ratchet 12 tightly.

[0073] Among them, the directions of the pawl 13 and the ratchet 12 can be configured according to actual needs. The accompanying drawings of this embodiment only exemplify some feasible solutions: the ratchet 12 is tilted, and its bottom end is close to the tube pressing plate 3, and the top end is far away from the tube pressing plate 3, but there is a certain horizontal spacing between the bottom end of the ratchet 12 and the tube pressing plate 3, which provides a certain operating space for the pawl 13 to unlock. Based on the tilt direction of the ratchet 12, when the pawl 13 and the ratchet 12 are engaged and pressed tightly, when force is directly applied to the tube pressing plate 3, only the downward force can drive the tube pressing plate 3 to move downward, and the force applied When the force is upward, the tube clamp 3 cannot be driven to move upward, thereby improving the limiting stability of the tube clamp 3 on the steel pipe; when the tube clamp 3 needs to be moved upward, the tube clamp 3 is slightly pressed downward, so that the pawl 13 moves obliquely downward along the ratchet 12 and rotates under pressure (the reset spring 14 is compressed at this time), until the pawl 13 is completely located in the gap between the ratchet 12 and the tube clamp 3, the direction of the pawl 13 is fixed by hand, and the tube clamp 3 is lifted to an appropriate position at the same time, and the pawl 13 is released. Under the action of the reset spring 14, the pawl 13 automatically presses against the corresponding ratchet 12 at this time. In order to facilitate the manual fixing of the direction of the pawl 13 in the above process, the rotation axis of the pawl 13 and the tube clamp 3 or at least part of the pawl 13 should be exposed in a space that can be operated by hand.

[0074] Reference Figure 9-10 The stabilizing plate 4 is arranged under the bottom plate 1-2 of the vehicle body 1 and is connected to the bottom plate 1-2 of the vehicle body 1 by a hanging rod 15. The hanging rod 15 can be configured as an electric telescopic rod or a manual telescopic rod or other device with a linear telescopic function. The height of the stabilizing plate 4 is directly adjusted by telescoping, so that when the vehicle body 1 moves, the stabilizing plate 4 does not hinder its movement. When the vehicle body 1 is stationary, the stabilizing plate 4 falls on the ground, thereby increasing the friction between the entire transfer vehicle and the ground and preventing the vehicle body 1 from moving unplanned.

[0075] Of course, the suspension rod 15 can also be configured as an ordinary rod. A servo motor 16 and a bidirectional lead screw 17 are arranged on the bottom plate 1-2 of the vehicle body 1. The servo motor 16 is used to drive the bidirectional lead screw 17 to rotate. Two groups of internal threaded sleeves 18 with opposite thread directions are sleeved on the bidirectional lead screw 17. The internal threaded sleeves 18 are at least partially slidably embedded in the bottom plate 1-2. The two groups of internal threaded sleeves 18 are respectively rotatably connected with the suspension rods 15, and the bottom ends of the two suspension rods 15 are respectively rotatably connected to the stabilizing plate 4. When the servo motor 16 drives the bidirectional lead screw 17 to rotate, the two groups of internal threaded sleeves 18 are restricted by the bottom plate 1-2 on the outer wall of the internal threaded sleeves 18, and the two groups of internal threaded sleeves 18 do not rotate, but move toward or away from each other along the length of the bidirectional lead screw 17. Driven by the two groups of internal threaded sleeves 18, the two suspension rods 15 rotate in opposite directions, thereby realizing the adjustment of the height of the stabilizing plate 4.

[0076] The construction direction of the bidirectional lead screw 17 can be configured according to actual usage requirements. For example, it can extend along the length of the base plate 1-2 or along the width of the base plate 1-2. Both can realize the lifting and lowering of the stabilizing plate 4 without hindering the movement of other components.

[0077] In this embodiment, the bidirectional lead screw 17 is configured to extend along the length of the bottom plate 1-2, and a transmission rod 19 parallel to the bidirectional lead screw 17 is arranged above the bottom plate 1-2. One end of the transmission rod 19 is rotatably arranged on the side plate 1-3 opposite to the open side 1-1, and the other end faces the open side 1-1. The bidirectional lead screw 17 and the transmission rod 19 are connected for transmission through a synchronous belt 20 and a synchronous wheel 21 arranged in the side plate 1-3. An internal threaded sleeve 22 is sleeved on the transmission rod 19, and the internal threaded sleeve 22 is arranged on the tube push plate 5. The end of the tube push plate 5 is configured to slide and abut against the inner wall of the vehicle body 1 (including the side plate 1-3 and the bottom plate 1-2); when the bidirectional lead screw 17 and the transmission rod 19 rotate synchronously, the internal threaded sleeve and the tube push plate 5 can only move along the length direction of the transmission rod 19 due to the limitation of the inner wall of the vehicle body 1, and approach or move away from the tube bracket 2. When it is necessary to unload the steel pipe, the pipe pushing plate 5 and the stabilizing plate 4 can be moved synchronously, so that the length of the steel pipe extending out of the vehicle body 1 is gradually increased, and the height of the stabilizing plate 4 is lowered to touch the ground. After the pipe pushing plate 5 and the stabilizing plate 4 are moved into place, the worker starts to unload the pipe manually. This not only increases the length of the steel pipe extending out of the vehicle body 1, thereby improving the convenience of the workers in unloading the pipe, but also improves the stability of the vehicle body 1 when unloading the pipe.

[0078] The method for transferring steel pipes using the transfer vehicle comprises the following steps:

[0079] Push the transfer vehicle to the pipe loading area and place the steel pipe on the pipe bracket 2;

[0080] Lower the pipe pressing plate 3 until it is tightly against the top surface of the steel pipe, and move the transfer vehicle to the pipe unloading area;

[0081] Gently press the tube pressing plate 3 to separate the pawl 13 from the ratchet 12, then fix the angle of the pawl 13 by hand, and at the same time lift the tube pressing plate 3 to a suitable height to separate the tube pressing plate 3 from the steel pipe;

[0082] Lower the stabilizing plate 4 to the ground, and move the pipe pushing plate 5 toward the steel pipe, and manually remove the steel pipe from the pipe bracket 2, completing the pipe loading and unloading process;
