Description

Technical Field

[0001] This utility model relates to the technical field of lifting devices, and more specifically to a lifting frame. Background Technology

[0002] A lifting frame is a mechanical device that uses a lifting mechanism to raise objects from a low place to a high place or lower them from a high place to a low place. It is widely used in industrial production, warehousing and logistics, construction and other fields, and is an important tool for realizing vertical transportation of materials.

[0003] Current lifting frames are relatively fixed in their setup, requiring direct erection at a certain height and location. They rely on motors and pulleys to lift the items and then on slide rails to move them. This type of lifting frame occupies a large amount of space and has limitations. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lifting frame to overcome the above-mentioned defects in the existing technology.

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

[0006] A lifting frame includes a support frame and a traction mechanism that slides on the support frame. The support frame includes a main frame and a sub-frame. A lifting mechanism is provided between the main frame and the sub-frame. The lifting mechanism is used to drive the main frame to move so that the main frame moves away from the sub-frame in a supported state, or to move the main frame closer to the sub-frame in a folded state.

[0007] Furthermore, the supporting mechanism includes a support arm, a first diagonal rod, and a first driving member. One end of the support arm is rotatably connected to the main frame, and the other end is rotatably connected to the sub-frame. One end of the first diagonal rod is rotatably connected to the support arm, and the other end is movably connected to the sub-frame. The first driving member is used to drive one end of the first diagonal rod connected to the sub-frame to move, so that the support arm rotates to stand up or rotates to fold onto the sub-frame.

[0008] Furthermore, the supporting mechanism also includes a second driving member, which is located at the sub-frame end away from the first driving member. When the main frame is in a folded state, the driving end of the second driving member is in contact with the lower surface of the main frame.

[0009] Furthermore, the sliding direction of the traction mechanism is defined as the first direction, and the length of the main frame in the first direction is greater than the length of the sub-frame in the first direction.

[0010] Furthermore, an auxiliary mechanism is provided between the main frame and the sub-frame. The auxiliary mechanism includes a second diagonal bar, one end of which is movably connected to the sub-frame, and the other end is rotatably connected to the end of the main frame that extends beyond the sub-frame.

[0011] Furthermore, the auxiliary mechanism also includes a carriage located on one side of the subframe, with one end of the second diagonal rod slidably connected inside the carriage.

[0012] Furthermore, the traction mechanism is located on the main frame, and the traction mechanism includes a traction slide and a traction winch. The traction slide has a hook at one end facing the sub-frame, and the traction winch is used to drive the traction slide to slide on the main frame.

[0013] Furthermore, the main frame is provided with a crossbeam along the first direction, the traction slide is slidably disposed on the crossbeam, and the main frame is also provided with a number of reinforcing arms for connecting the crossbeam and the main frame.

[0014] The beneficial effects of this utility model are as follows: by setting up a supporting mechanism, the main frame can be in a supported or folded state, which facilitates the use and storage of the main frame. Assuming it is applied to a concrete mixer truck, the sub-frame of the lifting frame is used to be installed on the vehicle body, and the main frame is used to lift the ton bag. By supporting the main frame, space can be provided for transporting the ton bag, and by folding the main frame, the overall height of the vehicle can be reduced. Attached Figure Description

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.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0022] Current lifting frames are relatively fixed, requiring direct erection at a certain height and position. They rely on motors and pulleys to lift the object, and then use slide rails to move it. This type of lifting frame occupies a large space and has limitations. Therefore, this utility model designs a lifting frame that... Figure 1 and Figure 2 As shown, the device includes a support frame and a traction mechanism that slides on the support frame. The support frame includes a main frame 1 and a secondary frame 2. A lifting mechanism is provided between the main frame 1 and the secondary frame 2. The lifting mechanism is used to drive the main frame 1 to move, so that the main frame 1 is in a supported state away from the secondary frame 2, or in a folded state close to the secondary frame 2. The lifting mechanism facilitates the use and storage of the main frame 1. Assuming it is applied to a concrete mixer truck, the secondary frame 2 of the lifting frame is used to be installed on the vehicle body, and the main frame 1 is used to lift the ton bag. By supporting the main frame 1, space can be provided for transporting the ton bag, and by folding the main frame 1, the overall height of the vehicle can be reduced.

[0023] like Figure 2As shown, the sliding direction of the traction mechanism is defined as the first direction. The length of the main frame 1 in the first direction is greater than the length of the sub-frame 2 in the first direction. The purpose is to extend the sliding distance of the traction mechanism to adapt to long-distance transportation. In addition, it is more suitable for installation on the concrete mixer truck body. The extended length of the main frame 1 makes it easier for workers to stand behind the truck body and hang the ton bags on the traction mechanism of the main frame 1. The supporting mechanism includes four support arms 3, a first diagonal bar 4, and a first driving component 5 (cylinder). The support arms 3 are located between the main frame 1 and the sub-frame 2. One end of the support arm 3 is rotatably connected to the main frame 1, and the other end is rotatably connected to the sub-frame 2. (To improve the stability of the main frame 1 when it is supported, the support arms 3 are set on the four sides of the sub-frame 2.) The first diagonal rod 4 is rotatably connected to the support arm 3 at one end and movably connected to the sub-frame 2 at the other end (the sub-frame 2 is provided with a slide rail arranged along the first direction, and the end of the first diagonal rod 4 is provided with a slider, and the end of the first diagonal rod 4 is rotatably connected to the slider). The first driving member 5 is used to drive the first diagonal rod 4 connected to the sub-frame 2 to move, so that the support arm 3 rotates to stand up or rotates to fold onto the sub-frame 2. Initially, the support arm 3 is stacked between the sub-frame 2 and the main frame 1. When the main frame 1 needs to be supported, the first driving member 5 drives the first diagonal rod 4 to push in the first direction. At this time, the support arm 3 moves from folded to upright. When the first diagonal rod 4 slides a certain distance, the support arm 3 is 90 degrees perpendicular to the sub-frame 2.

[0024] Since the main frame 1 is longer than the secondary frame 2, the first diagonal bar 4 in this utility model is in two sets, which are symmetrically arranged at the end of the main frame 1 that does not extend beyond the secondary frame 2. However, in order to facilitate the quick lifting of the main frame 1, the lifting mechanism also includes a second driving member 6 (cylinder). The second driving member 6 is located at the end of the secondary frame 2 away from the first driving member 5. When the main frame 1 is in a folded state, the driving end of the second driving member 6 is in contact with the lower surface of the main frame 1. When the first driving member 5 starts to push the first diagonal bar 4, the driving end of the second driving member 6 starts to lift the main frame 1 upward, and supports the main frame 1 synchronously with the first driving member 5.

[0025] Since the main frame 1 is longer than the secondary frame 2, when the weight of the object to be lifted is too large, in order to facilitate the stability of the main frame 1, this utility model also provides an auxiliary mechanism between the main frame 1 and the secondary frame 2. The auxiliary mechanism includes a second diagonal rod 7 and a slide 8. The slide 8 is located on one side of the secondary frame 2 and is arranged along the first direction. The slide 8 has a groove in the extension direction. One end of the second diagonal rod 7 is slidably connected in the groove of the slide 8, and the other end is rotatably connected to the end of the main frame 1 that extends beyond the secondary frame 2. When the main frame 1 is in a folded state, one end of the second diagonal rod 7 in the groove is located near the end of the first diagonal rod 4. When the main frame 1 is supported, one end of the second diagonal rod 7 in the groove slides along the direction of the groove until the second diagonal rod 7, the main frame 1, and the support arm 3 are arranged in a triangle, which can provide better stability.

[0026] In addition, the carriage 8 has a ramp section and a flat section. The ramp section is located near the first drive member 5, that is, the end of the carriage 8 near the first drive member 5 is higher than the end away from the first drive member 5. When the main frame 1 is in the folded state, one end of the second diagonal bar 7 in the slide groove is located on the ramp section. When the main frame 1 is supported, the end of the second diagonal bar 7 in the slide groove slides down along the ramp section, which facilitates the movement of the second diagonal bar 7 to support it until the second diagonal bar 7 slides into the flat section and continues to slide.

[0027] The traction mechanism is located on the main frame 1. The traction mechanism includes a traction slide 9 (traction vehicle) and a traction winch 10 (winch and winch rope). The traction slide 9 has a hook at one end facing the sub-frame 2. The main frame 1 is provided with a crossbeam 11 along the first direction. The traction winch 10 is used to drive the traction slide 9 to slide on the crossbeam 11. The main frame 1 is also provided with several reinforcing arms 12 for connecting the crossbeam 11 and the main frame 1 to improve the stability of the crossbeam 11.

[0028] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
