Description

Technical Field

[0001] This utility model relates to the field of gantry lifting equipment technology, and in particular to a 10T manual gantry lifting crane. Background Technology

[0002] The 10T manual gantry crane is a mechanical device used for vertical lifting and horizontal transport of heavy objects. It has a maximum lifting capacity of 10 tons and mainly relies on manual operation to lift and move heavy objects. It is suitable for some small factories, warehouses, workshops, construction sites and other places, and is also widely used in power engineering, construction, cargo loading and unloading and other fields.

[0003] The existing 10T manual gantry crane allows operators to push the main beam or side supports of the gantry crane to make the wheels roll on the ground or rails for horizontal movement, thus enabling the horizontal transport of heavy objects. However, during long-term use, the surface of the gantry crane wheels is prone to wear, resulting in a smooth wheel surface and a reduced coefficient of friction. This can easily cause the main body of the gantry crane to sway or shift during the lifting of heavy objects, affecting the overall stability of the gantry crane when lifting heavy objects. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a 10T manual gantry crane to solve the aforementioned problems.

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

[0006] The 10T manual gantry crane includes:

[0007] Two side supports provide overall support for the 10T manual gantry crane, transferring the weight of the 10T manual gantry crane to the ground. Reinforcing ribs are fixedly installed on the side supports to make the overall structure of the side supports stable.

[0008] The main lifting beam is fixedly installed on the top side of the two side supports, thus forming the whole of the 10T manual gantry crane. The main lifting beam can be equipped with a manual hoist, which can be used to lift heavy objects.

[0009] The four support legs, with the corresponding two support legs hinged to the reinforcing ribs of the side bracket, provide lateral support to the side bracket.

[0010] Two hinge plate assemblies are respectively mounted on the reinforcing ribs of the corresponding side brackets, and the hinge plate assemblies are configured to provide hinged support for the two support legs on the side brackets.

[0011] Two screw adjustment assemblies are respectively mounted on corresponding hinge plate assemblies. The screw adjustment assemblies are configured as two support legs on the side bracket for adjusting the side support angle.

[0012] Preferably, the two supporting legs on the reinforcing rib are fixedly installed with the same fixing rod, and the bottom end of the supporting leg is fixedly installed with a foot, which rests on the ground.

[0013] Preferably, the hinge plate assembly includes:

[0014] Two upright plates are fixedly installed on the reinforcing ribs of the side support;

[0015] A hinged cylinder, one end of which is hinged to two vertical plates, has a sliding cavity inside and two side openings on the hinged cylinder;

[0016] A slider is slidably mounted inside a sliding cavity, and a circular hole is provided on the slider.

[0017] Preferably, the cross-section of the sliding cavity on the hinged cylinder is arranged in a cross shape, and the slider is adapted to the sliding cavity.

[0018] Preferably, the fixing rod is slidably installed in the two side openings of the hinge cylinder, and the fixing rod moves through the circular hole on the slider.

[0019] Preferably, the screw adjusting assembly includes:

[0020] A rotating seat is fixedly mounted on one side of the slider;

[0021] A threaded rod, one end of which is rotatably mounted on one side of a rotating seat, and the other end of which is threaded through to the outside of a hinged cylinder and fitted with a rod disc.

[0022] Preferably, the side support has a bottom cavity on its bottom side, and multiple wheels are rotatably mounted on the inner wall of the bottom cavity.

[0023] This application involves hinged installation of two support legs on the reinforcing ribs of both side supports of a 10T manual gantry crane. A fixing rod between the two support legs passes through a slider inside a sliding cavity of a hinged cylinder mounted on the side support. When the threaded rod disc is turned, the slider can be driven to slide to the left within the sliding cavity of the hinged cylinder, thereby causing the bottom feet of the two support legs to press against the ground around the gantry crane, achieving lateral support for the side supports. This reduces the swaying or displacement of the gantry crane body during the lifting of heavy objects, improving the overall stability of the gantry crane when lifting heavy objects.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] This embodiment discloses a 10T manual gantry crane, including: as follows Figure 1 The diagram shows two side supports 100, a main lifting beam 101, and four support legs 200; as shown. Figure 5 The two hinge plate assemblies 300 and the two screw adjustment assemblies 400 are shown.

[0032] like Figure 1 As shown, the two side supports 100 provide overall support for the 10T manual gantry crane, transferring the weight of the 10T manual gantry crane to the ground. Reinforcing ribs 102 are fixedly installed on the side supports 100 to stabilize the overall structure of the side supports 100. The lifting main beam 101 is fixedly installed on the top side of the two side supports 100, thus forming the whole of the 10T manual gantry crane. The lifting main beam 101 can be equipped with a manual hoist, which can be used to lift heavy objects. By manually pulling the chain of the manual hoist or turning the rocker arm, the operator drives the sprocket or gear to rotate, so that the wire rope or chain is wound on the drum, thereby realizing the lifting or lowering of the heavy object (this is an existing mature technology and will not be described in detail here).

[0033] like Figure 4 As shown, two support legs 200 are hinged to the reinforcing ribs 102 of the side support 100. The bottom ends of the two support legs 200 are equipped with feet 202. The feet 202 at the bottom ends of the two support legs 200 rest on the ground around the gantry crane, thereby providing lateral support for the side support 100.

[0034] like Figure 5 As shown, the hinge plate assembly 300 is mounted on the reinforcing rib 102 of the side support 100. The hinge plate assembly 300 is configured to provide hinged support to the two support legs 200 on the side support 100. The hinge plate assembly 300 includes: two upright plates 301, a hinge cylinder 302, and a slider 303. The two upright plates 301 are fixedly mounted on the reinforcing rib 102 of the side support 100. One end of the hinge cylinder 302 is hinged to the two upright plates 301. A sliding cavity 3021 is provided inside the hinge cylinder 302. The cross-section of the sliding cavity 3021 is arranged in a cross shape. The slider 303 is slidably mounted inside the sliding cavity 3021. 3021 is compatible; for the connection between the two support legs 200 and the hinge cylinder 302, the same fixing rod 201 is fixedly installed between the two support legs 200. The slider 303 has a round hole 3031, and the hinge cylinder 302 has two side openings 3022. The fixing rod 201 is slidably installed in the two side openings 3022 of the hinge cylinder 302. At the same time, the fixing rod 201 moves through the round hole 3031 on the slider 303. This makes it easy for the fixing rod 201 on the two support legs 200 to drive the slider 303 to slide in the sliding cavity 3021 of the hinge cylinder 302, thereby realizing the hinge deflection adjustment of the two support legs 200.

[0035] Continue as Figure 5 As shown, the screw adjustment assembly 400 is mounted on the hinge plate assembly 300. The screw adjustment assembly 400 is configured to adjust the side support angle of the two support legs 200 on the side bracket 100. The screw adjustment assembly 400 includes a rotating seat 401 and a threaded rod 402. The rotating seat 401 is fixedly mounted on one side of the slider 303. One end of the threaded rod 402 is rotatably mounted on one side of the rotating seat 401, and the other end is threaded through the hinge cylinder 302 and fitted with a rod disc. By turning the lever disc at one end of the threaded rod 402, the operator can rotate the threaded rod 402, causing it to feed threadedly onto the hinge cylinder 302. This, in turn, causes the slider 303 to slide within the sliding cavity 3021 of the hinge cylinder 302. Consequently, the fixed rod 201 causes the two support legs 200 to deflect towards the side support 100, thereby causing the bottom feet 202 of the two support legs 200 to press against the ground around the gantry crane to the left, thus providing lateral support to the side support 100.

[0036] like Figure 2As shown, a bottom cavity 1001 is provided on the bottom side of the side support 100, and multiple wheels 103 are rotatably installed on the inner wall of the bottom cavity 1001; this facilitates the movement of the 10T manual gantry crane.

[0037] In this application, two support legs 200 are hinged to the reinforcing ribs 102 on both side supports 100 of a 10T manual gantry crane. The fixing rod 201 between the two support legs 200 passes through the slider 303 in the sliding cavity 3021 of the hinge cylinder 302 hinged to the side support 100. When the rod disc of the threaded rod 402 is turned, the slider 303 can be driven to slide to the left in the sliding cavity 3021 of the hinge cylinder 302. This causes the bottom feet 202 of the two support legs 200 to press against the ground around the gantry crane to the left, thus providing lateral support to the side supports 100. This reduces the swaying or displacement of the gantry crane body during the lifting of heavy objects and improves the overall stability of the gantry crane when lifting heavy objects.
