Description

Technical Field

[0001] The utility model relates to the technical field of measuring instrument auxiliary tools, in particular to a liftable handcart suitable for leveling measurement. Background Art

[0002] Currently, the most commonly used instruments for high-level leveling are electronic levels, indium tile rulers, ruler pads, and support rods. A single indium tile ruler typically weighs 5kg, and a single ruler pad weighs 5kg. Levelers often have to carry a single indium tile ruler, a pair of support rods, and a ruler pad, which is a heavy burden. Especially during third-class leveling, which uses a single-pass, dual-pivot observation method, levelers have to carry two 5kg ruler pads, a 5kg indium tile ruler, and a pair of support rods, for a total weight of 15kg. This adds a significant burden to levelers when working on long lines, reducing work efficiency. Furthermore, the measurement site is not suitable for larger carrying vehicles such as tricycles.

DETAILED DESCRIPTION

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Example 1

[0021] like Figure 1 The illustrated embodiment is a liftable trolley suitable for leveling measurement, comprising a base frame 1 and a side bracket. The base frame 1 is provided with a side bracket on the rear side, and two walking wheels 4 are provided at the bottom of the rear side of the base frame 1. The side bracket comprises at least two telescopic support rods. A storage basket 3 is fixedly provided on the base frame 1. The base frame 1 and the storage basket 3 are preferably made of stainless steel or aluminum alloy. The storage basket 3 is welded or riveted to the base frame 1. A support frame 301 is provided in the storage basket 3, and the support frame 301 and the side bracket are arranged parallel to each other.

[0022] Specifically, auxiliary wheels 5 are provided on the front side of the base frame 1 .

[0023] Specifically, a connecting frame 501 is provided at the front bottom of the base frame 1, and two auxiliary wheels 5 are respectively installed on both sides of the connecting frame 501. When the base frame 1 is placed horizontally, the lowest outer circumferences of the auxiliary wheels 5 and the running wheels 4 are on the same plane, playing a supporting role.

[0024] Specifically, the telescopic support rod includes a first support rod 2 and a second support rod 201. The first support rod 2 is a hollow structure, and the second support rod 201 is sleeved in the hollow cavity of the first support rod 2 and can move along the first support rod 2. The tops of the two second support rods are provided with a cross bar 203, and the cross bar 203 is covered with an anti-wear sleeve 204 to realize the telescopic function. The outer side surface of the first support rod 2 is provided with a through hole, and a positioning pin 202 is provided in the through hole. The second support rod 201 is provided with a positioning groove. When the positioning groove is opposite to the through hole, the positioning pin 202 is inserted into the positioning groove. Further, in order to prevent the positioning pin 202 from falling out, a spring is provided outside the positioning pin 202. One end of the spring is provided on the positioning pin 202, and the other end is provided on the inner side of the through hole. The spring elastic force presses the positioning pin into the hollow cavity of the first support rod 2. This is the existing technology and will not be repeated here to realize the positioning function, that is, the positions of the first support rod 2 and the second support rod 202 are relatively fixed to limit the length of the telescopic support rod.

[0025] Specifically, the second support rod 201 is provided with a plurality of positioning slots, which can achieve extension and retraction of different lengths.

[0026] Specifically, the height of the support frame 301 is lower than the height of the storage basket 3 .

[0027] Example 2

[0028] like Figure 2 The figure shows a liftable handcart suitable for leveling measurement. The support frame 301 is provided with a protective cover 302. The protective cover 302 is made of elastic wear-resistant rubber material or multi-layer cotton cloth or multi-layer non-woven fabric. The protective cover 302 is wrapped around the outer side of the support frame 3. On the one hand, it can protect the indium tile ruler 10 and the support rod leaning on it to prevent friction with the support frame 3 and avoid damage to the indium tile ruler 10. On the other hand, it also plays a certain anti-slip role to prevent the indium tile ruler 10 from shaking left and right. Generally, rivets or bolts can be passed through the protective cover 302, and the rivet head or nut at the other end can be fixed, or it can be fixed with a clip, etc. to achieve the fixing effect. This is the existing technology and will not be repeated here. When the protective cover 302 is worn, it is removed and the protective cover 302 is replaced.

[0029] Specifically, a protective layer 303 is laid in the storage cavity of the storage basket 3 away from the side bracket. The protective layer 303 is made of elastic wear-resistant rubber material or multiple layers of cotton cloth or multiple layers of non-woven fabric, and can be laid directly.

[0030] Example 3

[0031] like Figure 3 、 4 The figure shows a liftable trolley suitable for leveling measurement. A connecting shaft 502 is provided under the connecting frame 501. Two support plates 503 are welded to the connecting shaft 502. An angle is formed between the support plates 503. When the trolley is placed flat, it can touch the ground to strengthen the support. At the same time, it can prevent the trolley from moving when there is a slight collision.

[0032] like Figure 5 As shown, when in use, the indium tile ruler 10 and the support rod (not shown) are placed in the storage basket 3, and the bottom of the indium tile ruler 10 is located in the storage cavity between the support frame 301 and the front side wall of the storage basket 3. The height of the second support rod 201 is adjusted so that the side of the indium tile ruler 10 rests on the cross bar 203 of the side bracket and is fixed with a binding rope 6. The ruler pad 11 is placed in the storage cavity between the support frame 301 and the rear side wall of the storage basket 3. The ruler handler only needs to hold the indium tile ruler 10 and press it down. The auxiliary wheels 5 and the support plate are lifted, and the ruler handler pushes or pulls the indium tile ruler to move it to the desired position easily and effortlessly.

[0033] Specifically, the connecting frame includes two tripods, and the tripods are welded to the bottom of the base frame.

[0034] The present invention is not limited to the described implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solutions that are the same or similar to those of the present invention fall within the scope of protection of the present invention.

[0035] The technology, shape and structure that are not described in detail in this utility model are all well-known technologies.
