The invention relates to a gantry crane. The gantry crane comprises a gantry, wherein the gantry comprises two columns and a main beam; the two columns are arranged left and right at intervals; the main beam is bridged at the upper ends of the two columns; the gantry crane also comprises a hanging beam with length extending in the left-right direction; the hanging beam is used for installing corresponding hangers; the two ends of the hanging beam are respectively assembled on the two columns via corresponding guide structures by moving vertically in a guided manner; the gantry is provided with one or at least two transmission chains connected with the hanging beam through transmission so as to drive the hanging beams to go up and down; and the gantry is also provided with a chain wheel driving mechanism for driving one transmission chain to make cyclic action or all the chains to make cyclic action synchronously. The gantry crane provided by the invention can reduce the vertical distances between the main beam and the corresponding hangers.

The invention discloses a high-voltage transmission line deicer, relates to the field of transmission line maintenance equipment, and solves the problems that an existing deicer cannot achieve simplestructure, no increase to a power transmission line and high deicing rate simultaneously. The high-voltage transmission line deicer comprises a deicing clamp and deicing plates, the deicing plates arefixed to clamping parts of the deicing clamp, and the two deicing plates which are oppositely arranged are used for clamping and fixing the power transmission line so that an ice layer on the power transmission line is removed; each deicing plate is divided into a cutting part and a crushing part from bottom to top; the cutting part is composed of M arc-shaped cutters, the M arc-shaped cutters are sequentially and evenly distributed in the length direction of the power transmission line, and cutting edges of the arc-shaped cutters are semicircular and used for cutting the ice layer in the circumferential direction of the power transmission line. The crushing part is composed of N protrusions and used for clamping the cut ice layer so as to crush the ice layer. The high-voltage transmission line deicer is mainly used for cleaning the ice layer of the power transmission line.

The invention discloses a mouseproof optical cable which comprises a cable core, an outer sheath, and a soft armor layer. The outer sheath coats the cable core. The soft armor layer coats the outer sheath and is made of a PA12 material. The structure of the mouseproof optical cable is simple, the soft armor layer can effectively prevent the optical cable from being bitten, the integrity of the optical cable is ensured, the weight of the optical cable is not increased, and the production cost is effectively controlled.

The invention discloses a waist-mounted walking aid for patients with movement disorders of one lower limb, which comprises a core support installed on the waist, a belt for fixing the core support on the waist, and an energy storage device fixedly connected with the core support device, one end of the leg connecting piece connected to the energy storage device, a strap for fixing the leg connecting piece on the leg, and an adjustment mechanism for adjusting the preload of the energy storage device. The rehabilitation walking aid of the present invention adopts a waist-mounted design, which is easy to carry and wear, has a small overall weight, and does not increase the patient’s walking load. The core support is installed on the waist, which is convenient for patients with unsound upper limbs or injuries. The energy storage device stores energy when standing, and provides assistance when the affected limb steps forward, which is convenient for patients to walk. It can adapt to patients of different weights and heights. The adjustment mechanism can be adjusted quickly. patient use.

The invention relates to a power transmission tower angle steel connection joint. The power transmission tower angle steel connection joint comprises two principal materials, diagonal materials, diaphragm materials and auxiliary materials, wherein the principal materials are arranged in the vertical direction and serve as tower pillars, the diagonal materials are connected between the two adjacent principal materials, the included angle of the diagonal materials and the horizontal direction is smaller than 90 degrees, the diaphragm materials are horizontally arranged between the principal materials, and the auxiliary materials are connected with the principal materials, the diaphragm materials and / or the diagonal materials. The power transmission tower angle steel connection joint is characterized in that the principal materials which serve as the tower pillars comprise two or more principal material sections which are connected with one another in a head-to-tail mode; the tower pillars are composed of the principal material sections, the principal material sections comprise cross-shaped connecting plates which are perpendicular to each other and angle steel arranged on the crosswise intersected included angle portions. According to the power transmission tower angle steel connection joint, under the situation that the thicknesses of filler plates are different, connecting can be conducted among the principal material components according to the filler plate thicknesses obtained through actual calculation, the tower weight is reduced, it is guaranteed that the connection of the components is safe and reliable, and the economical efficiency of the tower is achieved.

The invention discloses a type of glass floating ball fixing clampers used for connecting glass floating balls and an anchor system main rope. The fixing clampers comprise two clamping boards which can be combined into a pair, and a plurality of bolt assemblies. The two clamping boards are provided with a pair of first bolt holes for connecting the clamping boards to the glass floating balls on the flange by the bolt assemblies. The clamping surfaces of the two clamping boards are provided with rope grooves for holding the main rope, wherein the cross sections of the rope grooves are arc-shaped. Second bolt holes are provided on the two sides of the grooves, for fasten the main rope with the bolt assemblies. With the clampers, reliable connections between the glass floating balls and the anchor system main rope can be realized. Because all the components are standard components, the clampers can be quickly installed in a standardized manner, without damaging the stability and firmnessof the original anchor system structures. Further, the invention discloses an anchor system comprising the glass floating ball fixing clampers.

The invention discloses a waist-worn rehabilitation walker, which comprises two core supports, a belt for fixing the core supports on the waist, an energy storage device fixedly connected with the core supports on the side of the affected limb, and An energy-assisted device for storing energy for the energy storage device when walking, two leg connectors respectively connected to the energy storage device and the energy-assist device, and a strap for fixing the other end of the leg connector to the leg. The invention adopts a waist-mounted design, which is easy to carry and wear, has a small overall weight, and will not increase the patient’s walking load. The core support is installed on the waist, which is convenient for patients with unsound upper limbs or injuries; It can increase the energy storage of the energy storage device when the healthy lower limbs are walking, and reduce the force of the legs when the affected limb is walking, so that the legs can be lifted easily, which is convenient for the patient to walk, and the assisting effect is obvious.
