Description

Technical Field

[0002] In the actual workshop work process, it is often necessary to move some heavy objects, such as the transportation of mechanical parts in machinery enterprises. There are certain difficulties in the transportation of these heavy objects. For example, when the transportation distance is not very far and does not require large motor vehicles to transport in batches, or when the heavy objects are on the platform on the second floor and the forklift cannot reach the platform on the second floor, the problem becomes particularly prominent.

[0003] (Refer to Fig.12 As shown in the figure, the T-shaped weight to be transported by the present invention includes a first body 6 and a second body 7, the end of the second body 7 is connected to the middle of the first body 6 to form a T-shape, the two ends of the first body 6 extend outward to form a first shaft 8 and a second shaft 9 respectively, forming a double shaft of the T-shaped weight, and the bottom end surface of the first body 6 is lower than the bottom end surface of the second body 7. Since the center of gravity of the T-shaped weight is not on the line between the first shaft and the second shaft, if the first shaft and the second shaft are only forked for transportation, the second body will be dragged on the ground and cannot be transported, or the end of the second body is lifted to the handrail by manpower to fix or remove it. For a weight of several hundred kilograms, it requires multiple people to assist in the operation or to use a lifting device to achieve it, and there are safety risks. In addition, in this way, the gravity of the T-shaped weight will be applied to the handrail all the time, and it is difficult for an operator to keep the handrail lifted up for a long time. It is difficult to keep the center of gravity of the T-shaped weight stable through the lever of the handrail. The operator is laborious and easily fatigued, and it is impossible to transport it over a long distance. It is inconvenient to lift or remove it, which is very likely to cause safety risks.

[0015] Another aspect of the present invention provides a T-shaped heavy object transporting method, which uses the T-shaped heavy object transporting cart.

[0016] The T-shaped weight comprises a first body and a second body, the end of the second body is connected to the middle of the first body to form a T shape, the two ends of the first body extend outward to form a first shaft portion and a second shaft portion respectively, and the bottom end surface of the first body is lower than the bottom end surface of the second body.

[0017] Specifically, the steps include: the first step: pushing the T-shaped heavy object transport cart to the bottom of the T-shaped heavy object, so that the first transport fork and the second transport fork are respectively located below the first shaft portion and the second shaft portion, and the second body is located above the protection pad of the horizontal axis of the hanger, and at this time, the upper hanging rods of the two handrails are not in the card slots of the vertical beam;

[0018] Step 2: Press down the handrail, the first carrying fork and the second carrying fork are respectively in contact with the first shaft and the second shaft to receive force, the first body is lifted, the second body is in contact with the protective pad of the horizontal axis of the hanger, and the T-shaped weight is supported on the first carrying fork, the second carrying fork and the horizontal axis of the hanger;

[0023] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0024] Firstly, the present invention has a simple structure and complete functions; it only requires one person and is easy to operate; it does not require a special drive system and only uses a simple lever mechanism, saving costs; it is durable and almost maintenance-free.

[0025] Secondly, the main function of the hanger body of the present invention is to support the second body of the T-shaped weight. The first shaft portion and the second shaft portion of the first body of the T-shaped weight are respectively placed on the first carrying fork and the second carrying fork, and the second body is placed on the protection pad of the hanger transverse axis. The hanger transverse axis of the hanger body is fixed on the first connecting plate and the second connecting plate, one end of the first connecting plate and the second connecting plate are respectively rotatably connected to the first axle and the second axle, and the other ends of the first connecting plate and the second connecting plate are respectively supported by universal wheels. The first body of the T-shaped weight is pressed on the carrying fork, and the second body of the T-shaped weight is placed on the hanger transverse axis. At this time, due to the gravity of the first body of the T-shaped weight, if the cart is to be moved, the operator needs to keep pressing the handrail. However, since the handrail, the carrying fork and the axle constitute a lever mechanism, which is a lever mechanism with the axle as the fulcrum, when the handrail is pressed down After the hanging rod is stuck in the slot, the horizontal axis of the hanger can be lifted so that the second body of the T-shaped weight is hung on the handrail rod. At this time, the universal wheel is off the ground, the first body of the T-shaped weight is pressed on the carrying fork, and the second body of the T-shaped weight is hung on the hanging rod of the handrail rod. At this time, the carrying fork, the handrail rod and the axle form a seesaw mechanism, and the first body and the second body of the T-shaped weight are kept balanced, so that the center of gravity of the T-shaped weight passes through the axle. In this way, the operator hardly needs to apply force to keep the T-shaped weight balanced, that is, almost no force needs to be applied to the handrail rod in the up and down directions, and only needs to apply force forward to push the vehicle, which is labor-saving, safe and convenient.

[0026] Thirdly, there is a torsion spring at the bottom of the hanger mechanism. When the handrail rod is pressed down, under the action of the thrust of the torsion spring, the hanging rod and the vertical beam contact and engage in the slot, and the slot of the hanging rod and the vertical beam is tightly engaged.

[0027] Fourthly, a release drive structure is provided to facilitate releasing the hanger mechanism with feet or hands to put down the second body of the T-shaped weight.

[0028] Fifth, one end of the first connecting plate and the second connecting plate are rotatably connected to the first axle and the second axle respectively, and the other ends of the first connecting plate and the second connecting plate are supported by universal wheels respectively. In this way, when the hanging rod of the handrail rod is not stuck in the slot, the whole T-shaped weight is stably supported by the walking wheels and the universal wheels. When the empty vehicle is pushed, if the universal wheels touch the ground, it is convenient to turn. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In this embodiment, the specifications of the arc-shaped grooves on the first carrying fork 41 and the second carrying fork 42 are different, which are specially used for the situation that the radii of the first shaft portion 8 and the second shaft portion 9 are different. More specifically, the radius of the arc-shaped groove of the first carrying fork 41 is larger than the radius of the arc-shaped groove on the second carrying fork 42; the specifications of the arc-shaped grooves on the first carrying fork 41 and the second carrying fork 42 can be further limited according to the shape and size of the double-outlet shaft of the T-shaped weight, so that the arc-shaped grooves on the first carrying fork (41) and the second carrying fork (42) are matched with the first shaft portion and the second shaft portion of the T-shaped weight respectively, and fit tightly.

[0045] Specifically, refer to 2, Figure 3 and Figure 4As shown; the hanger body includes a bottom beam 3, a first vertical beam 30, a second vertical beam 31, a hanger transverse axis 32 and a protection pad 33, the first vertical beam 30 and the second vertical beam 31 are respectively vertically arranged at the two ends of the bottom beam 3, the two ends of the hanger transverse axis 32 respectively pass through the first vertical beam 30 and the second vertical beam 31, and the hanger transverse axis 32 is rotatably connected with the first vertical beam 30 and the second vertical beam 31, the protection pad 33 is located in the middle position of the hanger transverse axis 32, and the two ends of the hanger transverse axis 32 are also provided with a first connecting plate 34 and a second connecting plate 35, one end of the first connecting plate (34) and the second connecting plate (35) are respectively rotatably connected with the first axle (51) and the second axle (52), the other ends of the first connecting plate (34) and the second connecting plate (35) are respectively supported by universal wheels (53), and the ends of the hanger transverse axis 32 are respectively sleeved with first A torsion spring 36 and / or a second torsion spring 37, wherein the two ends of the first torsion spring 36 are respectively connected to the first vertical beam 30 and the first connecting plate 34, and the two ends of the second torsion spring 37 are respectively connected to the second vertical beam 31 and the second connecting plate 35; the function of the first torsion spring 36 and / or the second torsion spring 37 is to enable the first vertical beam 30 and the second vertical beam 31 to obtain a forward force, so that the two hanging rods 39 contact the vertical beams and slide into the two slots 38 respectively, and are tightly engaged with the slots 38; the first vertical beam 30 and the second vertical beam 31 are both provided with slots 38, and the two handrails 11 are respectively provided with hanging rods 39 engaged with the slots 38, the openings of the slots 38 face the first carrying fork 41 and the second carrying fork 42, and the slots 38 are arranged in an oblique upward direction; so that the hanging rods 39 can slide into the two slots 38 respectively under the action of the first torsion spring 36 and the second torsion spring 37 and are not easy to fall out.

[0046] The main function of the hanger body is to support the second body 7 of the T-shaped weight. The first shaft portion 8 and the second shaft portion 9 of the first body 6 of the T-shaped weight are pressed on the first carrying fork 41 and the second carrying fork 42 respectively, and the second body 7 is placed on the protection pad 33 of the hanger transverse axis 32.

[0050] Embodiment 1:

[0051] The first vertical beam 30 and the second vertical beam 31 of the hanger mechanism 2 of the first embodiment are outside the two handrails 11. When the two handrails 11 rotate around the walking wheels 5, the height of the first vertical beam 30 and the second vertical beam 31 will not affect the bottom reinforcing rod 12; the first embodiment is released by stepping on the release rod 20; refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown;
