Description

Technical Field

[0001] This utility model relates to the field of pneumatic winches, and in particular to a pneumatic winch. Background Technology

[0002] A pneumatic winch is a winch device driven by compressed air, widely used in various applications requiring lifting, towing, and traction. Unlike traditional electric or manual winches, pneumatic winches use compressed air as a power source, offering a range of unique advantages and making them particularly suitable for industrial environments.

[0003] For example, a Chinese patent with patent number CN216471953U includes a substrate, a reciprocating unit, an auxiliary reciprocating unit, and a driving unit; the substrate has mounting plates symmetrically arranged on the left and right sides of the rear end of its upper surface, and a rotating cylinder is rotatably connected between the opposite inner sides of the two mounting plates through a rotating shaft; the reciprocating unit is disposed at the front end of the upper surface of the substrate; the auxiliary reciprocating unit is disposed on the inner top wall of the reciprocating unit.

[0004] The aforementioned cited document describes the use of a base plate to install and support the pneumatic winch as a whole. The pneumatic winch described in the document, like most traditional pneumatic winches, has a limited overall performance and lacks height and displacement adjustment, relying solely on external equipment for adjustment. Fixed-position pneumatic winches have poor operational adaptability and cannot be quickly adapted to different working conditions (such as different heights and horizontal positions), thus reducing overall work efficiency.

[0005] Therefore, a pneumatic winch is provided to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a pneumatic winch, which improves the operational adaptability of the pneumatic winch by making stable height and displacement adjustments.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A pneumatic winch includes a displacement adjusting mechanism;

[0009] A sliding table is mounted on the upper surface of the displacement adjustment mechanism, a base is mounted on the upper surface of the sliding table, and a pneumatic winch body is mounted on the upper surface of the base.

[0010] The displacement adjustment mechanism includes an adjustment seat, which is U-shaped and has linear guide rails mounted on its top two ends along its lateral direction; guide rail sliders are slidably fitted on both linear guide rails.

[0011] The sliding platform is disposed on the upper end face of the two guide rail sliders and is connected to the guide rail sliders;

[0012] The bottom of the adjusting seat is equipped with four sets of hydraulic cylinders.

[0013] Furthermore, the displacement adjustment mechanism also includes two sets of bearing seats disposed on the adjustment seat, each set of bearing seats being equipped with bearing components and rotatably connected to a threaded screw through the bearing components.

[0014] Furthermore, the lead screw is externally threaded with a lead screw nut, and the sliding table is positioned above the lead screw nut and connected to it.

[0015] Furthermore, a forward and reverse motor is mounted on the upper surface of the adjusting seat, and one end of the threaded screw passes through one of the bearing seats and extends to connect with the output end of the forward and reverse motor.

[0016] Furthermore, the four sets of hydraulic cylinders are arranged in pairs and distributed in a rectangular pattern on both sides of the bottom of the adjusting seat.

[0017] Furthermore, the output end of each cylinder is vertically arranged and connected to a support base, and the bottom of the support base is provided with anti-slip texture.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. Through the mutual movement and coordination of multiple structures set in the displacement adjustment mechanism, the sliding table mounted on the displacement adjustment mechanism can drive the base to make precise linear position adjustment. At this time, the pneumatic winch body installed on the base can also adjust its position accordingly. When the position of the work object, such as the hoisting object or the traction target, changes, the pneumatic winch body can be quickly moved to the appropriate position through the displacement adjustment mechanism without reinstallation or major adjustment of the construction plan. It can flexibly meet different needs in multiple working conditions or dynamic environments such as construction sites and ship decks.

[0020] 2. By setting four sets of hydraulic cylinders distributed at the four corners of the bottom of the adjusting seat, the four sets of hydraulic cylinders can be raised or lowered synchronously after being connected to the controller and synchronizer, thereby realizing the height adjustment of the pneumatic winch body. In use, by adjusting the hydraulic cylinders, the working height of the pneumatic winch body of this application can be flexibly adjusted according to the site conditions, adapting to traction or hoisting tasks with different height requirements, such as platforms of different levels and construction sites with obvious height differences. At the same time, it eliminates the need for frequent handling or modification of the winch due to the fixed installation height, thus improving the degree of operational freedom.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0029] First embodiment;

[0030] Reference Figure 1-5 As shown, a pneumatic winch in a preferred embodiment of the present invention includes a displacement adjustment mechanism 1;

[0031] A sliding table 3 is mounted on the upper end face of the displacement adjustment mechanism 1, a base 4 is mounted on the upper end face of the sliding table 3, and a pneumatic winch body 5 is mounted on the upper end face of the base 4.

[0032] The displacement adjustment mechanism 1 includes an adjustment seat 11, which is U-shaped and has linear guide rails 12 mounted on its top two ends along its lateral direction; guide rail sliders 13 are fitted and slidably disposed on both linear guide rails 12.

[0033] The sliding table 3 is disposed on the upper end face of the two guide rail sliders 13 and is connected to the guide rail sliders 13;

[0034] Four sets of hydraulic cylinders 2 are installed at the bottom of the adjusting seat 11.

[0035] In this embodiment, the sliding table 3 mounted on the displacement adjustment mechanism 1 can drive the base 4 to make precise linear position adjustments. At this time, the pneumatic winch body 5 installed on the base 4 can also make position adjustments. When the position of the work object, such as the hoisting object or the traction target, changes, the pneumatic winch body 5 can be quickly moved to a suitable position through the displacement adjustment mechanism 1 without reinstallation or major adjustments to the construction plan. It can flexibly meet different needs in multiple working conditions or dynamic environments such as construction sites and ship decks.

[0036] Furthermore, by adjusting the hydraulic cylinder 2, the working height of the pneumatic winch body 5 of this application can be flexibly adjusted according to the site conditions, adapting to traction or hoisting tasks with different height requirements, such as platforms of different levels and construction sites with significant height differences. At the same time, the winch does not need to be frequently moved or modified due to the fixed installation height, thus improving the degree of freedom of operation.

[0037] In a preferred embodiment, such as the example embodiment Figure 4 As shown, the base 4 has several threaded holes, and the pneumatic winch body 5 has positioning holes corresponding to these threaded holes. The pneumatic winch body 5 can be bolted onto the base 4 using matching bolts.

[0038] Second embodiment;

[0039] Reference Figure 2-4 As shown, the displacement adjustment mechanism 1 also includes two sets of bearing seats 14 disposed on the adjustment seat 11. Each set of bearing seats 14 is equipped with bearing components and is rotatably connected to a threaded screw 15 through the bearing components.

[0040] In this embodiment,

[0041] Third embodiment;

[0042] Reference Figure 5 As shown, the threaded screw 15 is externally threaded and fitted with a screw nut, and the sliding table 3 is positioned above the screw nut and connected to it.

[0043] In this embodiment, when the threaded screw 15 rotates, it is limited by the guide rail slider 13 by two linear guide rails 12. In conjunction with the connection between the guide rail slider 13 and the sliding table 3, the screw nut, which is threaded on the outside of the threaded screw 15, can drive the sliding table 3 to perform linear displacement adjustment along the thread stroke of the threaded screw 15.

[0044] Fourth embodiment;

[0045] Reference Figure 1 As shown, a forward and reverse motor 16 is mounted on the upper end face of the adjusting seat 11, and one end of the threaded screw 15 passes through one of the bearing seats 14 and extends to connect with the output end of the forward and reverse motor 16.

[0046] In this embodiment, the forward and reverse motor 16 can be used to adjust the rotation of the lead screw 15.

[0047] Furthermore, the threaded screw 15 in this application is equipped with a motor controller and a synchronizer, which can be used to control the number of rotations and the direction of rotation of the forward and reverse motor 15. In use, the power connection method of the forward and reverse motor 15 is existing technology, and the control circuit and synchronous rotation method can be implemented by those skilled in the art through simple programming, which is common knowledge in the field. Since it is only used without modification, the control method and circuit connection will not be described in detail.

[0048] Fifth embodiment;

[0049] Reference Figure 1 As shown, the four sets of hydraulic cylinders 2 are arranged in pairs and distributed in a rectangular pattern on both sides of the bottom of the adjusting seat 11.

[0050] In this embodiment, four sets of hydraulic cylinders 2 are distributed at the four corners of the bottom of the adjusting seat 11. When the hydraulic cylinders 2 are connected to the controller and the synchronization valve, they can be raised or lowered synchronously to maintain the horizontal state of the displacement adjusting mechanism 1, avoid tilting or overturning, and the adjustment process is smooth with little vibration, which is particularly suitable for hoisting operations with certain load requirements.

[0051] Sixth embodiment;

[0052] Reference Figure 1 As shown, the output end of each cylinder 2 is vertically arranged and connected to a support base 21, and the bottom of the support base 21 is provided with anti-slip texture.

[0053] In this embodiment, the anti-slip texture provided at the bottom of the support base 21 can ensure the stable installation of the pneumatic winch body 5 of this application on the hoisting platform, thereby preventing the pneumatic winch body 5 of this application from shifting.

[0054] Specific implementation process:

[0055] Step 1: When the user is installing the pneumatic winch body 5, the pneumatic winch body 5 is positioned and assembled on the base 4 by using the appropriate bolts, so that the base 4 stably supports the pneumatic winch body 5.

[0056] Step 2: The user adjusts the displacement adjustment mechanism 1, which allows the sliding table 3 on the displacement adjustment mechanism 1 to drive the base 4 to make linear displacement adjustment along the stroke range of the displacement adjustment mechanism 1. During this period, the user connects the power supply and controller to the forward and reverse motor 16, which drives the threaded screw 15 to rotate. When the threaded screw 15 rotates, it is limited by the two linear guide rails 12 on the guide rail slider 13. With the connection between the guide rail slider 13 and the sliding table 3, the screw nut with the thread engaged on the outside of the threaded screw 15 can drive the sliding table 3 and the base 4 as a whole to make linear displacement adjustment along the thread stroke of the threaded screw 15. At this time, the pneumatic winch body 5 installed on the base 4 can follow the adjustment.

[0057] Step 3: The user connects the controller and the synchronization valve to the four sets of hydraulic cylinders 2, so that the four sets of hydraulic cylinders 2 can be raised or lowered synchronously, thereby adjusting the height of the displacement adjustment mechanism 1. At this time, the pneumatic winch body 5 installed on the displacement adjustment mechanism 1 can also be adjusted in height.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
