Abstract

The utility model relates to a forklift tooth sleeve. The forklift tooth sleeve comprises a tooth sleeve main body, wherein anti-friction and anti-slip material layers are arranged at a position where the upper surface of the tooth sleeve main body contacts steel coils and at a position where the upper inner wall of the tooth sleeve main body contacts forklift teeth; the section of the anti-friction and anti-slip layer on the upper surface of the tooth sleeve main body is arc; the tooth sleeve main body is made of channel steel and steel plates and is adhered to the anti-friction and anti-slip layers; and the anti-friction and anti-slip layers are Shore 90A polyurethane elastomers. As the anti-friction and anti-slip layers are arranged inside and outside the forklift tooth sleeve, when the forklift tooth sleeve is used, scrape marks and pressing marks are not generated on cold rolled steel coils, the forklift tooth sleeve does not fall off the forklift teeth, and the steel coils do not fall off the forklift teeth. Tests prove that the novel forklift tooth sleeve is convenient to assemble and disassemble in the using process, is falling-resistant and anti-slip, is durable and reaches the design standards, and obvious scrap marks are not generated on the contact surface between the forklift tooth sleeve and the rolled steel coils.

Description

Fork truck tooth cover

Technical field

The utility model relates to a kind of fork truck that is used for the coil loading and unloading, and especially a kind of cold rolling coil surface that can prevent produces fork truck tooth cover of impression and preparation method thereof.

Background technology

The Luojing ancillary firm is a last port group breakbulk steel terminal heteroatom, and in the coil loading and unloading, cold rolling coil requires in loading and unloading operation and must not the prong of forklift directly be contacted preventing to produce impression with cold rolling coil is surperficial, and outside face must not have any grazing vestige.

A general cold rolling coil weight is below 8 tons; As add the mode of boom accessory with 16 ton forklifts; Can only shovel a coil at every turn, the very big wasting of resources occur, and as adopting 16 tons of forklifts chock plate or rubber method on prong; In operation, still have the cold rolling coil surface phenomena of scratch to take place, cause the goods damage quality problems.Therefore.The novel forklift tooth cover that needs a kind of pressure mark-proof of exploitation is to stop this type of phenomenon.

This novel forklift tooth cover adopts special material to make the tooth cover, and cold rolling coil and prong are isolated, and prevents that cold rolling coil from producing scratch and impression; Shovel 2 coil operations respectively with anti-friction pair of prong cover, promptly 2 coils of an operation cycle improve loading and unloading operation efficient.Because existing prong cover body interior all is a metallic material with prong, friction coefficient about 0.15, friction force can't offset fork truck in traveling process because the power of fork truck braking or accessory generation when tilting causes prong to come off easily.Need to adopt a kind of anticreep and anti-skidding prong cover.Anticreep is meant mainly and prevents that the fork truck tooth from overlapping to deviate from from prong that anti-skidding being meant prevents that coil from putting from the fork truck tooth.

The utility model content

The utility model is that a kind of fork truck tooth cover will be provided, and uses this fork truck tooth cover can prevent that cold rolling coil from producing scratch and impression, can prevent that again fork truck tooth cover from deviating from and prevent that coil from putting from the fork truck tooth from prong.

The technical scheme of the utility model is: a kind of fork truck tooth cover, comprise tooth cover main body, above the tooth cover main body with the coil contact position and go up inwall and fork truck toe joint synapsis is respectively equipped with the anti-collision scrape along ribband bed of material.

The cross section of the anti-collision scrape along ribband bed of material above the tooth cover main body is a circular arc.

Tooth cover main body is processed by channel-section steel and steel plate.

Be connected through stickup between tooth cover main body and the anti-collision scrape along ribband bed of material.

The anti-collision scrape along ribband bed of material is the polyurethane elastomer of Shao Shi 90A (shore hardness 90A type).

The beneficial effect of the utility model is: at the inside and outside anti-collision scrape along ribband bed of material that is provided with of fork truck tooth cover; During use; This fork truck tooth cover can prevent that cold rolling coil from producing scratch and impression, can prevent that again fork truck tooth cover from deviating from and prevent that coil from putting from the fork truck tooth from prong.Through test, this novel forklift tooth is enclosed within the use easy to loading and unloading, non-skid, and do not have obvious scratch with the coil contact surface, and durable in use, reached design standard.

The specific embodiment

One. the development standard of the fork truck tooth cover of the utility model

At present, the vehicle that cold rolling coil loading and unloading are used is 16 tons of KALMAR fork trucks, is prototype with this fork truck, makes novel forklift tooth cover.

Because forklift tine is rigid contact when contacting with coil, and the prong superficial hardness is bigger, stays scratch at the coil inside face easily, so decision adopts special material to make the tooth cover, cold rolling coil and prong are isolated, prevent that cold rolling coil from producing scratch and impression; Simultaneously, novel forklift tooth cover also should possess the function of slip-off preventing merit and convenient disassembly.

According to above standard, the utility model has adopted like Fig. 1 to structure shown in Figure 3.Fork truck tooth cover comprises tooth cover main body 1, the anti-collision scrape along ribband bed of material 2, and tooth cover main body 1 is processed by channel-section steel and steel plate.

Above the tooth cover main body 1 and coil contact position and last inwall and fork truck toe joint synapsis are respectively equipped with the anti-collision scrape along ribband bed of material 2.The cross section of the anti-collision scrape along ribband bed of material 2 above the tooth cover main body 1 is a circular arc.The anti-collision scrape along ribband bed of material 2 is the polyurethane elastomer of Shao Shi 90A.Be connected through stickup between tooth cover main body 1 and the anti-collision scrape along ribband bed of material 2.

Two. the manufacture craft of fork truck tooth cover

(1) tooth cover main body

In order to make the tooth cover possess certain degree of hardness, convenient disassembly is again simultaneously selected No. 45 steel manufacturing materials as tooth cover main body for use, through mapping record oad, and makes with the connection mode of welding.

(2) the anti-grazing material of tooth cover

Through to the comparison of Study of indexes such as load-carrying capacity, percentage elongation, rebound degree, Akron wearing and tearing, determine to select for use Shao Shi 90A polyurethane elastomer as anti-collision scrape along anti-slip material.Its material composition is: polyester, TDI (isocyanates), different aggressiveness.Production and processing method is two step method: I: dimerization reaction II: vulcanization reaction.

(3) tooth overlaps the bonding manufacture craft of the anti-friction ribband bed of material

Tooth cover main body 1 surfaces externally and internally is carried out clean; And brushing 422 adhesivess on the inside and outside wall on the tooth cover main body 1; Put into then baking oven with the mould of the anti-collision scrape along ribband bed of material 2 that will make be heated to 120 ℃ together; Elastic polyurethane with the die casting Shao Shi 90A of the anti-collision scrape along ribband bed of material 2 is body formed, and the polyurethane elastomer of Shao Shi 90A and tooth cover main body 1 are bonded together; The demoulding then, and carried out post-cure 12 hours.

The purpose of post-cure is to make rubber further crosslinked, improves rubber mechanical property and compressive permanent set performance etc.
