Description
TECHNICAL FIELD
[0001] The utility model relates to an unmanned carrier, in particular to an AGV trolley. BACKGROUND
[0002] AGV trolley (Automated Guided Vehicle) is a kind of unmanned short-distance transport tool, also called unmanned carrier or automatic guided vehicle.It can travel along the prescribed guide path by electromagnetic or optical automatic guide device, with safety protection and various transfer functions.AGV trolley is mainly applied to factory production line, for automatically carrying material, improves production efficiency.
[0003] With the development of AGV industry, customers' requirements for the size of AGV are smaller and smaller, while the load demand is larger and larger.For the AGV of latent traction type, the main traction force comes from the friction force formed by the normal pressure provided by driving wheel with the help of vehicle body weight to tow material trolley or load.The existing conventional mobile equipment or AGV frame adopts the mode of profile welding+thin sheet metal shell, and the vehicle body weight adopts the mode of steel block / lead block.For the vehicle body with large space, cement block is also used to increase the self-weight.The former is relatively high in processing and cost, and the iron block is not easy to unify the standard due to space form, and the latter is relatively low in cost but needs several times space of iron block.
[0004] In view of the above, it is necessary to improve the existing AGV vehicle body structure. INVENTION CONTENTS
[0005] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an AGV trolley, and the purpose of designing the vehicle body structure of the AGV is to reduce installation strength and adapt to different vehicle model requirements.
[0006] To solve the above technical problems, the utility model realizes the following scheme: the utility model provides an AGV trolley, which comprises a frame main body, at least two groups of supporting wheels supporting the frame main body and a power wheel module driving the frame main body to move, the frame main body is provided with a plurality of separate cavities, one of the separate cavities is used as a counterweight bin, and the counterweight bin accommodates a counterweight object.
[0007] The counterweight object comprises a counterweight box and a plurality of counterweight units filled in the counterweight box.
[0008] Further, the counterweight unit comprises one or a combination of box structure counterweight unit, bag structure counterweight unit, spherical structure counterweight unit and irregular package counterweight unit.
[0009] Further, the bag structure counterweight unit comprises:
[0010] a packaging bag;
[0011] Multiple iron filings were filled into the packaging bag.
[0012] Furthermore, the packaging bag includes one or a combination of plastic bags and woven bags.
[0013] Furthermore, the inner layer of the packaging bag is a plastic bag, and its outer layer is a woven bag.
[0014] Furthermore, the plastic bag is a PE bag and has at least one layer.
[0015] Furthermore, the woven bag is a snakeskin bag with at least one layer.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. The counterweight of the AGV trolley of this utility model adopts a counterweight unit. The independent counterweight unit is easy to pick up and take down, and does not require the use of lifting equipment to disassemble and assemble the counterweight, thus reducing labor intensity.
[0018] 2. The counterweight unit adopts a bag-like structure, which can ensure the sealing and reliability of the counterweight unit. Attached Figure Description
[0019] Figure 1 This is an assembly diagram of the AGV trolley of this utility model.
[0020] Figure 2 This is an exploded view of the AGV trolley of this utility model.
[0021] The attached diagram is labeled as follows: frame body 1, support wheel 2, drive wheel module 3, cavity 11, counterweight 12. Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] Example 1: The specific structure of this utility model is as follows:
[0025] Please refer to the appendix. Figures 1-2 This utility model discloses an AGV (Automated Guided Vehicle) trolley, comprising a frame body 1, at least two sets of support wheels 2 supporting the frame body 1, and a power wheel module 3 for driving the frame body 1 to move. The frame body 1 is a one-piece structure formed by bending and welding 5mm sheet metal.
[0026] The frame body 1 has multiple cavities 11, one of which serves as a counterweight compartment. For example... Figure 2 As shown, there are four compartments 11. The compartment 11 at the front of the vehicle is used to install the control module. The second compartment and the end compartment are empty. The counterweight compartment is located between the second compartment and the end compartment. The control panel is connected to the cover of the first compartment, and the covers of the second to the end compartments have two openable covers.
[0027] The counterweight compartment contains 12 counterweights.
[0028] The counterweight 12 includes a counterweight box and multiple counterweight units filled in the counterweight box. The counterweight units include one or a combination of boxed counterweight units, bagged counterweight units, spherical counterweight units, and irregularly packaged counterweight units.
[0029] The bagged counterweight unit includes a packaging bag and multiple iron pellets filled inside the packaging bag.
[0030] The packaging bag includes one or a combination of plastic bags and woven bags. Preferably, the packaging bag is a combination structure, with an inner layer of plastic bag and an outer layer of woven bag. The plastic bag is a PE bag with at least one layer, and the woven bag is a snakeskin bag with at least one layer.
[0031] Preferably, the PE bag is provided in one layer, and the snakeskin bag is provided in two layers. The packaging bag composed of two layers of snakeskin bag and one layer of PE bag has good sealing performance, high packaging strength, and is not easily damaged.
[0032] The packaging bags are small and lightweight, making them easy to handle. These small bags can be filled with counterweight boxes of varying sizes.
