Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a weight for load test used for confirming the safety of personnel such as lifts and gondola or cableway for material transportation.

(Prior Art) As part of a cableway safety test, a lift, a gondola, etc. are operated, and, for example, one person lays a cushion rubber mat on the carrying seat of the moving lift or the floor surface of the gondola, and the other one A test has been conducted in which a weight (for example, 30 kg per piece) formed in a substantially quadrangular shape is placed on the mat for a fixed capacity or a fixed weight and the operation is performed for a fixed time.

(Issues to be solved by the invention) However, loading and unloading of the above weights must be done within a short time in order to operate the lifts and gondola, and it requires a large number of people, so the weight must be accurately placed on the laid mat. It must be placed and work must be done so that the corners and sides of the weight do not directly touch the seat or interior surface. Furthermore, vibrations during start and stop, driving etc. There is a problem in terms of workability and safety that the weight may be displaced due to the weight, and the seat surface may be damaged at the corners of the weight.

The present invention is intended to solve the above problems,
It is an object of the present invention to provide a weight for weight test that does not require a mat and that does not easily damage the corners and sides of the weight even if it hits the seat or the interior surface.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention has a bottom plate made of an elastic material and a side wall formed by standing up the periphery of the bottom plate. The protective cover provided so as to form an acute angle with the bottom plate is elastically pressure-bonded to the lower peripheral surface of the weight body formed so that the opposing side wall forms an acute angle with the bottom surface, and the opposing side wall of the protective cover is attached. It is characterized in that the weight for weight test is configured so as to cover the lower part of the weight main body by engaging with the opposite side wall of the weight main body.

(Function) Since a protective cover is attached to the bottom of the weight body,
The corners and sides of the weight are covered to prevent contact with a seat or the like and prevent damage to them.

(Example) Hereinafter, the present invention will be described with reference to the drawings shown as an example.

The weight body 1 for load test is made of iron or an appropriate metal, and in the case of a lift, it weighs about half the average weight of 60 kg per person.
It is a block of 30 kg, and the peripheral side surface is raised from the bottom surface so as to form an acute angle with respect to the bottom surface to form a substantially rectangular pyramid-shaped quadrangular body, and a round bar-shaped handle is arranged in the upper center. The grip portion 2 is formed, and the lower side surface is formed as the adhered portion 3 which is recessed from the upper side surface by, for example, about 5 mm.

Reference numeral 4 denotes a protective cover used in the present invention, which is made of soft vinyl chloride, rubber, synthetic rubber, or other synthetic resin having appropriate elasticity, and the side wall 5 corresponding to the adherend 3. It is formed so as to rise from the bottom plate 6 and a pair of opposing two side walls 5, 5 of the side walls 5 form an acute angle with the bottom plate 6. The side walls 5 and the bottom plate 6 have such a size and shape that the peripheral surfaces thereof can be elastically pressure-bonded to the adhered portion 3 to adhere and hold the relevant portion, and preferably the corners and sides are rounded. It has a saucer shape and has at least one drain hole 7 in the bottom plate 6, and is composed of, for example, a side wall having a thickness of about 5 mm and a bottom plate having a thickness of about 8 mm.

Then, the protective cover 4 is attached to the adhered portion 3 of the weight body 1.
If the pair of side walls 5 and 5 are elastically pressure-bonded to the peripheral surface of the adhered portion 3 and the inner surface of the side wall 5 is engaged with the peripheral surface, the side walls 5 and 5 are securely adhered and held without slipping downward. Then, if desired, the weight body 1 and the protective cover 4 are integrated by fixing with an adhesive, a screw or the like, so that it is not necessary to lay a mat on the seat or the floor surface, and the protective cover 4 is attached to the weight. Since it is covered with the corners and sides of the main body 1, it is possible to prevent direct contact of the metal part with the carrier seat of the lift, the floor surface of the gondola, and the like, and prevent damage caused by the contact. Since the protective cover 4 is made of an elastic material, friction is large, it is hard to slip, it is safe, and the metallic noise generated during loading can be prevented, and the working environment can be improved.

In addition, the protective cover of the weight for load test may be formed to cover the entire weight main body in addition to the above-mentioned embodiment, or may be configured to cover only the lower corners and sides. Alternatively, the weight may be directly adhered to the weight body by dipping, coating or the like.

Further, the protective cover may be used not only for a load test of a cableway such as a lift or a gondola, but also for a calibration load test of a weighing hopper for measuring the weight.

(Effects of the Invention) As described above, according to the present invention, the number of workers can be reduced because the cushioning mat is not required, and the weight of the load test is handled and the seat, floor and other interior surfaces can be treated. It is possible to prevent the possibility of damage, reduce the risk of injury or bruise to the human body, and improve workability and safety.
